Divide this in three sed scripts + instead: a one liner that removes the trailing spaces, one for + #defines, and then the last for #undef. + + The real speed up comes from the fact that the #define script + starts by checkin if the current input line has a #define, and if + not the script immediately goes to the next line, without running + the rest of the script as was the case before. Equally for the + #undef script. + + Note that this way, users that don't use #define templates don't + pay too much the overhead, since the sed script `realizes' quickly + there are no #define lines. My test case runs in 0.32s with + #define templates, and 0.24s without. To improve this common + case, the whole code for #define templates is conditionalized by a + proper egrep call. The result runs is 0.24s, i.e., almost no cost + at all. + + I made one dangerous change that I carefully evaluated before + commiting: the sed scripts are cut at 48 lines instead of 12 as + before. This produces here docs of about 4Kb. I checked many + `configure's and they all have big here documents, much bigger + than the 12 lines (for instance AC_FUNC_MMAP produces a 150 lines + long, 3800+ character here document). So I moved to the well + known HP UX sed limitations: no more than 100 commands, and there + are two commands per line now, plus a two command preamble. The + speed up is noticeable. + + * acgeneral.m4 (AC_OUTPUT_HEADERS): Remove the ac_e + family. + Changed ac_uD and ac_dD to `...;t t', instead of `...g'. + Instead of creating `conftest.vals' with both ac_e, ac_d, + and ac_u family, preprocess to strip the trailing spaces, and + create `conftest.defines' with the ac_d family, and then + `conftest.undefs' for the ac_e family. + Break up both `conftest.defines' and `conftest.undefs'.

The stable +release never changes except for patches that address bugs or +emergencies. Patches change the patchlevel and the release date. + +New features are developed in snapshot releases. These are called +postfix-2.3-yyyymmdd where yyyymmdd is the release date (yyyy=year, +mm=month, dd=day). Patches are never issued for snapshot releases; +instead, a new snapshot is released. + +The mail_release_date configuration parameter (format: yyyymmdd) +specifies the release date of a stable release or snapshot release. + +Main changes with Postfix version 2.2 +------------------------------------- + +This is a summary of the changes. These and more are detailed in +the following sections of this document. + +- TLS and IPv6 support are now built into Postfix, based on code +from third-party patches. + +- Extended query interface for LDAP, MySQL and PostgreSQL with free +form SQL queries, and domain filters to reduce unnecessary lookups. + +- SMTP client-side connection reuse. This can dramatically speed +up deliveries to high-volume destinations that have some servers +that respond, and some non-responding mail servers. + +- By default, Postfix no longer rewrites message headers in mail +from remote clients. This includes masquerading, canonical mapping, +replacing "!" and "%" by "@", and appending the local domain to +incomplete addresses. Thus, spam from poorly written software no +longer looks like it came from a local user. + +- When your machine does not have its own domain name, Postfix can +now replace your "home network" email address by your ISP account +in outgoing SMTP mail, while leaving your email address unchanged +when sending mail to someone on the local machine. + +- Compatibility workarounds: you can now selectively turn off ESMTP +features such as AUTH or STARTTLS in the Postfix SMTP client or +server, without having to "dumb down" other mail deliveries, and +without having to use transport maps for outgoing mail. + +- Remote SMTP client resource control (the anvil server). This +allows you to limit the number of connections, or the number of +MAIL FROM and RCPT TO commands that an SMTP client can send per +unit time. + +- Support for CDB, SDBM and NIS+ databases is now built into Postfix +(but the CDB and SDBM libraries are not). + +- New SMTP access control features, and more. + +Major changes - critical +------------------------ + +BEFORE upgrading from an older release you MUST stop Postfix, unless +you're running a Postfix 2.2 snapshot release that already has +Postfix 2.2 IPV6 and TLS support. + +AFTER upgrading from an older release DO NOT copy the old +master.cf/main.cf files over the new files. Instead, you MUST let +the Postfix installation procedure update the existing configuration +files with new service entries. + +[Incompat 20041118] The master-child protocol has changed. The +Postfix master daemon will log warnings about partial status updates +if you don't stop and start Postfix. + +[Incompat 20041023, 20041009] The queue manager to delivery agent +protocol has changed. Mail will remain queued if you do not restart +the queue manager. + +[Incompat 20050111] The upgrade procedure adds the tlsmgr service +to the master.cf file. This service entry is not compatible with +the Postfix/TLS patch. + +[Feature 20040919] The upgrade procedure adds the discard service +to the master.cf file. + +[Feature 20040720] The upgrade procedure adds the scache (shared +connection cache) service to the master.cf file. + +Major changes - IPv6 support +---------------------------- + +[Feature 20050111] Postfix version 2.2 IP version 6 support based +on the Postfix/IPv6 patch by Dean Strik and others. IPv6 support +is always compiled into Postfix on systems that have Postfix +compatible IPv6 support. On other systems Postfix will simply use +IP version 4 just like it did before. See the IPV6_README document +for what systems are supported, and how to turn on IPv6 in main.cf. + +[Incompat 20050111] Postfix version 2.2 IPv6 support differs from +the Postfix/IPv6 patch by Dean Strik in a few minor ways. + +- Network protocol support including DNS lookup is selected with +the inet_protocols parameter instead of the inet_interfaces parameter. +This is needed so that Postfix will not attempt to deliver mail via +IPv6 when the system has no IPv6 connectivity. + +- The lmtp_bind_address6 feature was omitted. The Postfix LMTP +client will be absorbed into the SMTP client, so there is no reason +to keep adding features to the LMTP client. + +- The CIDR-based address matching code was rewritten. The new +behavior is believed to be closer to expectation. The results may +be incompatible with that of the Postfix/IPv6 patch. + +[Incompat 20050117] The Postfix SMTP server now requires that IPv6 +addresses in SMTP commands are specified as [ipv6:ipv6address], as +described in RFC 2821. + +Major changes - TLS support +--------------------------- + +[Feature 20041210] Postfix version 2.2 TLS support, based on the +Postfix/TLS patch by Lutz Jaenicke. TLS support is not compiled +in by default. For more information about Postfix 2.2 TLS support, +see the TLS_README document. + +[Incompat 20041210] Postfix version 2.2 TLS support differs from +the Postfix/TLS patch by Lutz Jaenicke in a few minor ways. + +- main.cf: Use btree instead of sdbm for TLS session cache databases. + + Session caches are now accessed only by the tlsmgr(8) process, + so there are no concurrency issues. Although Postfix still has + an SDBM client, the SDBM library (1000 lines of code) is no longer + included with Postfix. + + TLS session caches can use any database that can store objects + of several kbytes or more, and that implements the sequence + operation. In most cases, btree databases should be adequate. + + NOTE: You cannot use dbm databases. TLS session objects are too + large. + +- master.cf: Specify unix instead of fifo for the tlsmgr service type. + This change is automatically made by the Postfix upgrade procedure. + + The smtp(8) and smtpd(8) processes use a client-server protocol + in order to access the tlsmgr(8)'s pseudo-random number generation + (PRNG) pool, and in order to access the TLS session cache databases. + Such a protocol cannot be run across fifos. + +[Feature 20050209] The Postfix SMTP server policy delegation protocol +now supplies TLS client certificate information after successful +verification. The new policy delegation protocol attribute names +are ccert_subject, ccert_issuer and ccert_fingerprint. + +[Feature 20050208] New "check_ccert_maps maptype:mapname" feature +to enforce access control based on hexadecimal client certificate +fingerprints. + +Major changes - SMTP client connection cache +-------------------------------------------- + +[Feature 20040720] SMTP client-side connection caching. Instead of +disconnecting immediately after a mail transaction, the Postfix +SMTP client can save the open connection to the scache(8) connection +cache daemon, so that any SMTP client process can reuse that session +for another mail transaction. See the CONNECTION_CACHE_README +document for a description of configuration and implementation. + +This feature introduces the scache (connection cache) server, which +is added to your master.cf file when you upgrade Postfix. + +[Feature 20040729] Opportunistic SMTP connection caching. When a +destination has a high volume of mail in the active queue, SMTP +connection caching is enabled automatically. This is controlled +with a new configuration parameter "smtp_connection_cache_on_demand" +(default: yes). + +[Feature 20040723] Per-destination SMTP connection caching. This +is enabled with the smtp_connection_cache_destinations parameter. +The parameter requires "bare" domain names or IP addresses without +"[]" or TCP port, to avoid a syntax conflict between host:port and +maptype:mapname entries. + +[Feature 20040721] The scache(8) connection cache manager logs cache +hit and miss statistics every $connection_cache_status_update_time +seconds (default: 600s). It reports the hit and miss rates for +lookups by domain, as well as for lookups by network address. + +Major changes - address rewriting +--------------------------------- + +[Feature 20050206] Support for address rewriting in outgoing SMTP +mail (headers and envelopes). This is useful for sites that have a +fantasy Internet domain name such as localdomain.local. Mail +addresses that use fantasy domain names are often rejected by mail +servers. + +The smtp_generic_maps feature allows you to replace a local mail +address (user@localdomain.local) by a valid Internet address +(account@isp.example) when mail is sent across the Internet. The +feature has no effect on mail that is sent between accounts on the +local machine. The syntax is described in generic(5) and a detailed +example is in the STANDARD_CONFIGURATION_README document, the section +titled "Postfix on hosts without a real Internet hostname". + +[Feature 20041023] By default, Postfix no longer rewrites message +headers in mail from remote clients. This includes masquerading, +canonical mapping, replacing "!" and "%" by "@", and appending the +local domain to incomplete addresses. Thus, spam from poorly written +software no longer looks like it came from a local user. + +By default, Postfix rewrites message header addresses only when the +client IP address matches the local machine's interface addresses, +or when mail is submitted with the Postfix sendmail(1) command. + +Postfix rewrites message headers in mail from other clients only +when the remote_header_rewrite_domain parameter specifies a domain +name (such as "domain.invalid"); this domain is appended to incomplete +addresses. Rewriting also includes masquerading, canonical mapping, +and replacing "!" and "%" by "@". + +To get the behavior before Postfix 2.2 (always append Postfix's own +domain to incomplete addresses in message headers, always subject +message headers to canonical mapping, address masquerading, and +always replace "!" and "%" by "@") specify: + +/etc/postfix/main.cf: + local_header_rewrite_clients = static:all + +If you must rewrite headers in mail from specific clients then you +can specify, for example, + +/etc/postfix/main.cf: + local_header_rewrite_clients = permit_mynetworks, + permit_sasl_authenticated, permit_tls_clientcerts, + check_address_map hash:/etc/postfix/pop-before-smtp + +Postfix always appends local domain information to envelope addresses +(as opposed to header addresses), because an unqualified envelope +address is effectively local for the purpose of delivery, and for +the purpose of replying to it. + +Full details are given in ADDRESS_REWRITING_README, and in the +postconf(5) manual. For best results, point your browser at the +ADDRESS_REWRITING_README.html file and navigate to the section +titled " To rewrite message headers or not, or to label as invalid". + +[Incompat 20050212] When header address rewriting is enabled, Postfix +now updates a message header only when at least one address in that +header is modified. Older Postfix versions first parse and then +un-parse a header so that there may be subtle changes in formatting, +such as the amount of whitespace between tokens. + +[Incompat 20050227] Postfix no longer changes message header labels. +Thus, FROM: or CC: are no longer replaced by From: or Cc:. + +[Feature 20040827] Finer control over canonical mapping with +canonical_classes, sender_canonical_classes and +recipient_canonical_classes. These specify one or more of +envelope_sender, header_sender, envelope_recipient or header_recipient. +The default settings are backwards compatible. + +Major changes - SMTP compatibility controls +------------------------------------------- + +[Feature 20041218] Fine control for SMTP inter-operability problems, +by discarding keywords that are sent or received with the EHLO +handshake. Typically one would discard "pipelining", "starttls", +or "auth" to work around systems with a broken implementation. +Specify a list of EHLO keywords with the smtp(d)_discard_ehlo_keywords +parameters, or specify one or more lookup tables, indexed by remote +network address, with the smtp(d)_discard_ehlo_keyword_address_maps +parameters. + +Note: this feature only discards words from the EHLO conversation; +it does not turn off the actual features in the SMTP server. + +Major changes - database support +-------------------------------- + +[Feature 20050209] Extended LDAP, MySQL and PgSQL query interface +with free form SQL queries, the domain filter optimization that was +already available with LDAP and more. This code was worked on by +many people but Victor Duchovni took the lead. See the respective +{LDAP,MYSQL,PGSQL}_README and {ldap,mysql,pgsql}_table documents. + +[Feature 20041210] You can now dump an entire database with the new +postmap/postalias "-s" option. This works only for database types +with Postfix sequence operator support: hash, btree, dbm, and sdbm. + +[Feature 20041208] Support for CDB databases by Michael Tokarev. +This supports both Michael's tinycdb and Daniel Bernstein's cdb +implementations, but neither of the two implementations is bundled +with Postfix. + +[Feature 20041023] The NIS+ client by Geoff Gibbs is now part of +the Postfix source tree. Details are given in the nisplus_table(5) +manual page. + +[Feature 20040827] Easier use of the proxymap(8) service with the +virtual(8) delivery agent. The virtual(8) delivery agent will +silently open maps directly when those maps can't be proxied for +security reasons. This means you can now specify "virtual_mailbox_maps += proxy:mysql:whatever" without triggering a fatal error in the +virtual(8) delivery agent. + +Major changes - remote SMTP client resource control +--------------------------------------------------- + +[Incompat 20041009] The smtpd_client_connection_limit_exceptions +parameter is renamed to smtpd_client_event_limit_exceptions. Besides +connections it now also applies to per-client message rate and +recipient rate limits. + +[Feature 20041009] Per SMTP client message rate and recipient rate +limits. These limit the number of MAIL FROM or RCPT TO requests +regardless of whether or not Postfix would have accepted them +otherwise. The user interface (smtpd_client_message_rate_limit and +smtpd_client_recipient_rate_limit) is similar to that of the existing +per SMTP client connection rate limit, and the same warnings apply: +these features are to be used to stop abuse, and must not be used +to regulate legitimate mail. More details can be found in the +postconf(5) manual. + +Major changes - remote SMTP client access control +------------------------------------------------- + +[Feature 20050209] The Postfix SMTP server policy delegation protocol +now supplies TLS client certificate information after successful +verification. The new policy delegation protocol attribute names +are ccert_subject, ccert_issuer and ccert_fingerprint. + +[Feature 20050208] New "check_ccert_maps maptype:mapname" feature +to enforce access control based on hexadecimal client certificate +fingerprints. + +[Feature 20050203] New "permit_inet_interfaces" access restriction +to allow access from local IP addresses only. This is used for the +default, purist, setting of local_header_rewrite_clients (rewrite +only headers in mail from this machine). + +[Feature 20050203] New "sleep time-in-seconds" pseudo access +restriction to block zombie clients with reject_unauthorized_pipelining +before the Postfix SMTP server sends the SMTP greeting. See postconf(5) +for example. This feature is not available the stable Postfix 2.2 +release, but it is documented here so that it will not get lost. + +[Feature 20041118] New "smtpd_end_of_data_restrictions" feature +that is invoked after the client terminates the SMTP DATA command. +The syntax is the same as with "smtpd_data_restrictions". In the +SMTPD policy delegation request, the message size is the actual +byte count of the message content, instead of the message size +announced by the client in the MAIL FROM command. + +Major changes - SASL authentication +----------------------------------- + +[Feature 20040827] Better SMTP client control over the use of SASL +mechanisms. New smtp_sasl_mechanism_filter mechanism to shorten the +list of SASL mechanisms from a remote server to just those that the +local SASL library can actually use. + +Major changes - header/body patterns +------------------------------------ + +[Feature 20050205] REPLACE action in header_checks and body_checks, +to replace a message header or body line. See header_checks(5) for +details. + +Major changes - local delivery +------------------------------ + +[Feature 20040621] Control over the working directory when executing +an external command. With the pipe(8) mailer, specify directory=pathname, +and with local(8) specify "command_execution_directory = expression" +where "expression" is subject to $home etc. macro expansion. The +result of macro expansion is restricted by the set of characters +specified with execution_directory_expansion_filter. + +Major changes - mail delivery attributes +---------------------------------------- + +[Feature 20041218] More client attributes for delivery to command +with the local(8) and pipe(8) delivery agents: client_hostname, +client_address, client_protocol, client_helo, sasl_method, sasl_sender, +and sasl_username. With local(8), attribute names must be specified +in upper case. + +Major changes - package creation +-------------------------------- + +[Feature 20050203] To create a ready-to-install package for +distribution to other systems you can now use "make package" or +"make non-interactive-package", instead of invoking the internal +postfix-install script by hand. See the PACKAGE_README file for +details. + +Major changes - performance +--------------------------- + +[Incompat 20050117] Only the deferred and defer queue directories +are now hashed by default, instead of eight queue directories. This +may speed up Postfix boot time on low-traffic systems without +compromising performance under high load too much. Hashing must be +turned on for the defer and deferred queue directories, because +those directories contain lots of files when undeliverable mail is +backing up. + +[Incompat 20040720] The default SMTP/LMTP timeouts for sending RSET +are reduced to 20s. + +Major changes - miscellaneous +----------------------------- + +[Feature 20050203] Safety: Postfix no longer tries to send mail to +the fallback_relay when the local machine is MX host for the mail +destination. See the postconf(5) description of the fallback_relay +feature for details. + +[Incompat 20041023] Support for the non-standard Errors-To: return +addresses is now removed from Postfix. It was already disabled by +default with Postfix version 2.1. Since Errors-To: is non-standard, +there was no guarantee that it would have the desired effect with +other MTAs. + +[Feature 20040919] A new discard(8) mail delivery agent that makes +throwing away mail easier and more efficient. It's the Postfix +equivalent of /dev/null for mail deliveries. On the mail receiving +side, Postfix already has a /dev/null equivalent in the form of the +DISCARD action in access maps and header_body_checks. + +[Feature 20040919] Access control for local mail submission, for +listing the queue, and for flushing the queue. These features are +controlled with authorized_submit_users, authorized_mailq_users, +and with authorized_flush_users, respectively. The last two controls +are always permitted for the super-user and for the mail system +owner. More information is in the postconf(5) manual. + +[Incompat 20040829] When no recipients are specified on the command +line or via the -t option, the Postfix sendmail command terminates +with status EX_USAGE and produces an error message instead of +accepting the mail first and bouncing it later. This gives more +direct feedback in case of a common client configuration error. + diff --git a/static/netbsd/man2/RELEASE_NOTES-3.2 b/static/netbsd/man2/RELEASE_NOTES-3.2 new file mode 100644 index 00000000..876d4b7a --- /dev/null +++ b/static/netbsd/man2/RELEASE_NOTES-3.2 @@ -0,0 +1,180 @@ +This is the Postfix 3.2 (stable) release. + +The stable Postfix release is called postfix-3.2.x where 3=major +release number, 2=minor release number, x=patchlevel.

With each change come updated +tests to ensure that future changes will not 'break' compatibility +with past behavior. + +Major changes - address mapping +------------------------------- + +[Feature 20170128] Postfix 3.2 fixes the handling of address +extensions with email addresses that contain spaces. For example, +the virtual_alias_maps, canonical_maps, and smtp_generic_maps +features now correctly propagate an address extension from "aa +bb+ext"@example.com to "cc dd+ext"@other.example, instead of +producing broken output. + +Major changes - header/body_checks +---------------------------------- + +[Feature 20161008] "PASS" and "STRIP" actions in header/body_checks. +"STRIP" is similar to "IGNORE" but also logs the action, and "PASS" +disables header, body, and Milter inspection for the remainder of +the message content. Contributed by Hobbit. + +Major changes - log analysis +---------------------------- + +[Feature 20160330] The collate.pl script by Viktor Dukhovni for +grouping Postfix logfile records into "sessions" based on queue ID +and process ID information. It's in the auxiliary/collate directory +of the Postfix source tree. + +Major changes - maps support +---------------------------- + +[Feature 20160527] Postfix 3.2 cidr tables support if/endif and +negation (by prepending ! to a pattern), just like regexp and pcre +tables. The primarily purpose is to improve readability of complex +tables. See the cidr_table(5) manpage for syntax details. + +[Incompat 20160925] In the Postfix MySQL database client, the default +option_group value has changed to "client", to enable reading of +"client" option group settings in the MySQL options file. This fixes +a "not found" problem with Postfix queries that contain UTF8-encoded +non-ASCII text. Specify an empty option_group value (option_group +=) to get backwards-compatible behavior. + +[Feature 20161217] Stored-procedure support for MySQL databases. +Contributed by John Fawcett. See mysql_table(5) for instructions. + +[Feature 20170128] The postmap command, and the inline: and texthash: +maps now support spaces in left-hand field of the lookup table +"source text". Use double quotes (") around a left-hand field that +contains spaces, and use backslash (\) to protect embedded quotes +in a left-hand field. There is no change in the processing of the +right-hand field. + +Major changes - milter support +------------------------------ + +[Feature 20160611] The Postfix SMTP server local IP address and +port are available in the policy delegation protocol (attribute +names: server_address, server_port), in the Milter protocol (macro +names: {daemon_addr}, {daemon_port}), and in the XCLIENT protocol +(attribute names: DESTADDR, DESTPORT). + +[Feature 20161024] smtpd_milter_maps support for per-client Milter +configuration that overrides smtpd_milters, and that has the same +syntax. A lookup result of "DISABLE" turns off Milter support.

To get the old behavior, +set TZ=UTC in main.cf:import_environment (this override is not +recommended, as it affects all Postfix utities and daemons). + +Major changes - safety +---------------------- + +[Incompat 20161227] For safety reasons, the sendmail -C option must +specify an authorized directory: the default configuration directory, +a directory that is listed in the default main.cf file with +alternate_config_directories or multi_instance_directories, or the +command must be invoked with root privileges (UID 0 and EUID 0). +This mitigates a recurring problem with the PHP mail() function. + +Major changes - sasl +-------------------- + +[Feature 20160625] The Postfix SMTP server now passes remote client +and local server network address and port information to the Cyrus +SASL library.

It sets the shell +variable +.I ignoreeof +which causes the shell to not log me off if I hit ^D. Rather, +I use the +.I logout +command to log off of the system. +By setting the +.I mail +variable, I ask the shell to watch for incoming mail to me. Every 5 minutes +the shell looks for this file and tells me if more mail has arrived there. +An alternative to this is to put the command +.DS +biff y +.DE +in place of this +.I set; +this will cause me to be notified immediately when mail arrives, and to +be shown the first few lines of the new message. +.PP +Next I set the shell variable `time' to `15' causing the shell to automatically +print out statistics lines for commands which execute for at least 15 seconds +of \s-2CPU\s+2 time. The variable `history' is set to 10 indicating that +I want the shell to remember the last 10 commands I type in its +.I "history list" , +(described later). +.PP +I create an +.I alias +``ts'' which executes a +\fItset\fR\|(1) command setting up the modes of the terminal. +The parameters to +.I tset +indicate the kinds of terminal which I usually use when not on a hardwired +port. I then execute ``ts'' and also use the +.I stty +command to change the interrupt character to ^C and the line kill +character to ^U. +.PP +I then run the `msgs' program, which provides me with any +system messages which I have not seen before; the `\-f' option here prevents +it from telling me anything if there are no new messages. +Finally, if my mailbox file exists, then I run the `mail' program to +process my mail. +.PP +When the `mail' and `msgs' programs finish, the shell will finish +processing my +.I \&.login +file and begin reading commands from the terminal, prompting for each with +`% '. +When I log off (by giving the +.I logout +command) the shell +will print `logout' and execute commands from the file `.logout' +if it exists in my home directory. +After that the shell will terminate and \s-2UNIX\s0 will log +me off the system. +If the system is not going down, I will receive a new login message. +In any case, after the `logout' message the shell is committed to terminating +and will take no further input from my terminal. +.NH 2 +Shell variables +.PP +The shell maintains a set of +.I variables. +We saw above the variables +.I history +and +.I time +which had values `10' and `15'. +In fact, each shell variable has as value an array of +zero or more +.I strings. +Shell variables may be assigned values by the set command. It has +several forms, the most useful of which was given above and is +.DS +set name=value +.DE +.PP +Shell variables may be used to store values which are to +be used in commands later through a substitution mechanism. +The shell variables most commonly referenced are, however, those which the +shell itself refers to. +By changing the values of these variables one can directly affect the +behavior of the shell. +.PP +One of the most important variables is the variable +.I path. +This variable contains a sequence of directory names where the shell +searches for commands. +The +.I set +command with no arguments +shows the value of all variables currently defined (we usually say +.I set) +in the shell. +The default value for path will be shown by +.I set +to be +.DS +% set +.ta .75i +argv () +cwd /usr/bill +home /usr/bill +path (. /usr/ucb /bin /usr/bin) +prompt % +shell /bin/csh +status 0 +term c100rv4pna +user bill +% +.so tabs +.DE +This output indicates that the variable path points to the current +directory `.' and then `/usr/ucb', `/bin' and `/usr/bin'. +Commands which you may write might be in `.' (usually one of +your directories). +Commands developed at Berkeley, live in `/usr/ucb' +while commands developed at Bell Laboratories live in `/bin' and `/usr/bin'. +.PP +A number of locally developed programs on the system live in the directory +`/usr/local'. +If we wish that all shells which we invoke to have +access to these new programs we can place the command +.DS +set path=(. /usr/ucb /bin /usr/bin /usr/local) +.DE +in our file +.I \&.cshrc +in our home directory. +Try doing this and then logging out and back in and do +.DS +set +.DE +again to see that the value assigned to +.I path +has changed. +.FS \(dg +Another directory that might interest you is /usr/new, which contains +many useful user-contributed programs provided with Berkeley Unix. +.FE +.PP +One thing you should be aware of is that the shell examines each directory +which you insert into your path and determines which commands are contained +there. Except for the current directory `.', which the shell treats specially, +this means that if commands are added to a directory in your search path after +you have started the shell, they will not necessarily be found by the shell. +If you wish to use a command which has been added in this way, you should +give the command +.DS +rehash +.DE +to the shell, which will cause it to recompute its internal table of command +locations, so that it will find the newly added command. +Since the shell has to look in the current directory `.' on each command, +placing it at the end of the path specification usually works equivalently +and reduces overhead. +.PP +Other useful built in variables are the variable +.I home +which shows your home directory, +.I cwd +which contains your current working directory, +the variable +.I ignoreeof +which can be set in your +.I \&.login +file to tell the shell not to exit when it receives an end-of-file from +a terminal (as described above). +The variable `ignoreeof' +is one of several variables which the shell does not care about the +value of, only whether they are +.I set +or +.I unset. +Thus to set this variable you simply do +.DS +set ignoreeof +.DE +and to unset it do +.DS +unset ignoreeof +.DE +These give the variable `ignoreeof' no value, but none is desired or required. +.PP +Finally, some other built-in shell variables of use are the +variables +.I noclobber +and +.I mail. +The metasyntax +.DS +> filename +.DE +which redirects the standard output of a command +will overwrite and destroy the previous contents of the named file. +In this way you may accidentally overwrite a file which is valuable. +If you would prefer that the shell not overwrite files in this +way you can +.DS +set noclobber +.DE +in your +.I \&.login +file. +Then trying to do +.DS +date > now +.DE +would cause a diagnostic if `now' existed already. +You could type +.DS +date >! now +.DE +if you really wanted to overwrite the contents of `now'. +The `>!' is a special metasyntax indicating that clobbering the +file is ok.\(dg +.FS +\(dgThe space between the `!' and the word `now' is critical here, as `!now' +would be an invocation of the +.I history +mechanism, and have a totally different effect. +.FE +.NH 2 +The shell's history list +.PP +The shell can maintain a +.I "history list" +into which it places the words +of previous commands. +It is possible to use a notation to reuse commands or words +from commands in forming new commands. +This mechanism can be used to repeat previous commands or to +correct minor typing mistakes in commands. +.PP +The following figure gives a sample session involving typical usage of the +history mechanism of the shell. +.KF +.DS +% cat bug.c +main() + +{ + printf("hello); +} +% cc !$ +cc bug.c +"bug.c", line 4: newline in string or char constant +"bug.c", line 5: syntax error +% ed !$ +ed bug.c +29 +4s/);/"&/p + printf("hello"); +w +30 +q +% !c +cc bug.c +% a.out +hello% !e +ed bug.c +30 +4s/lo/lo\e\en/p + printf("hello\en"); +w +32 +q +% !c \-o bug +cc bug.c \-o bug +% size a.out bug +a.out: 2784+364+1028 = 4176b = 0x1050b +bug: 2784+364+1028 = 4176b = 0x1050b +% ls \-l !* +ls \-l a.out bug +\(mirwxr\(mixr\(mix 1 bill 3932 Dec 19 09:41 a.out +\(mirwxr\(mixr\(mix 1 bill 3932 Dec 19 09:42 bug +% bug +hello +% num bug.c | spp +spp: Command not found. +% ^spp^ssp +num bug.c | ssp + 1 main() + 3 { + 4 printf("hello\en"); + 5 } +% !! | lpr +num bug.c | ssp | lpr +% +.DE +.KE +In this example we have a very simple C program which has a bug (or two) +in it in the file `bug.c', which we `cat' out on our terminal. We then +try to run the C compiler on it, referring to the file again as `!$', +meaning the last argument to the previous command. Here the `!' is the +history mechanism invocation metacharacter, and the `$' stands for the last +argument, by analogy to `$' in the editor which stands for the end of the line. +The shell echoed the command, as it would have been typed without use of +the history mechanism, and then executed it. +The compilation yielded error diagnostics so we now run the editor on the +file we were trying to compile, fix the bug, and run the C compiler again, +this time referring to this command simply as `!c', which repeats the last +command which started with the letter `c'. If there were other +commands starting with `c' done recently we could have said `!cc' or even +`!cc:p' which would have printed the last command starting with `cc' +without executing it. +.PP +After this recompilation, we ran the resulting `a.out' file, and then +noting that there still was a bug, ran the editor again. After fixing +the program we ran the C compiler again, but tacked onto the command +an extra `\-o bug' telling the compiler to place the resultant binary in +the file `bug' rather than `a.out'. In general, the history mechanisms +may be used anywhere in the formation of new commands and other characters +may be placed before and after the substituted commands. +.PP +We then ran the `size' command to see how large the binary program images +we have created were, and then an `ls \-l' command with the same argument +list, denoting the argument list `\!*'. +Finally we ran the program `bug' to see that its output is indeed correct. +.PP +To make a numbered listing of the program we ran the `num' command on the file `bug.c'. +In order to compress out blank lines in the output of `num' we ran the +output through the filter `ssp', but misspelled it as spp. To correct this +we used a shell substitute, placing the old text and new text between `^' +characters. This is similar to the substitute command in the editor. +Finally, we repeated the same command with `!!', but sent its output to the +line printer. +.PP +There are other mechanisms available for repeating commands. The +.I history +command prints out a number of previous commands with numbers by which +they can be referenced. There is a way to refer to a previous command +by searching for a string which appeared in it, and there are other, +less useful, ways to select arguments to include in a new command. +A complete description of all these mechanisms +is given in the C shell manual pages in the \s-2UNIX\s0 Programmer's Manual. +.NH 2 +Aliases +.PP +The shell has an +.I alias +mechanism which can be used to make transformations on input commands. +This mechanism can be used to simplify the commands you type, +to supply default arguments to commands, +or to perform transformations on commands and their arguments. +The alias facility is similar to a macro facility. +Some of the features obtained by aliasing can be obtained also +using shell command files, but these take place in another instance +of the shell and cannot directly affect the current shells environment +or involve commands such as +.I cd +which must be done in the current shell. +.PP +As an example, suppose that there is a new version of the mail program +on the system called `newmail' +you wish to use, rather than the standard mail program which is called +`mail'. +If you place the shell command +.DS +alias mail newmail +.DE +in your +.I \&.cshrc +file, the shell will transform an input line of the form +.DS +mail bill +.DE +into a call on `newmail'. +More generally, suppose we wish the command `ls' to always show +sizes of files, that is to always do `\-s'. +We can do +.DS +alias ls ls \-s +.DE +or even +.DS +alias dir ls \-s +.DE +creating a new command syntax `dir' +which does an `ls \-s'. +If we say +.DS +dir ~bill +.DE +then the shell will translate this to +.DS +ls \-s /mnt/bill +.DE +.PP +Thus the +.I alias +mechanism can be used to provide short names for commands, +to provide default arguments, +and to define new short commands in terms of other commands. +It is also possible to define aliases which contain multiple +commands or pipelines, showing where the arguments to the original +command are to be substituted using the facilities of the +history mechanism. +Thus the definition +.DS +alias cd \'cd \e!* ; ls \' +.DE +would do an +.I ls +command after each change directory +.I cd +command. +We enclosed the entire alias definition in `\'' characters to prevent +most substitutions from occurring and the character `;' from being +recognized as a metacharacter. +The `!' here is escaped with a `\e' to prevent it from being interpreted +when the alias command is typed in. +The `\e!*' here substitutes the entire argument list to the pre-aliasing +.I cd +command, without giving an error if there were no arguments. +The `;' separating commands is used here +to indicate that one command is to be done and then the next. +Similarly the definition +.DS +alias whois \'grep \e!^ /etc/passwd\' +.DE +defines a command which looks up its first argument in the password file. +.PP +.B Warning: +The shell currently reads the +.I \&.cshrc +file each time it starts up. If you place a large number of commands +there, shells will tend to start slowly. A mechanism for saving the shell +environment after reading the \fI\&.cshrc\fR file and quickly restoring it is +under development, but for now you should try to limit the number of +aliases you have to a reasonable number... 10 or 15 is reasonable, +50 or 60 will cause a noticeable delay in starting up shells, and make +the system seem sluggish when you execute commands from within the editor +and other programs. +.NH 2 +More redirection; >> and >& +.PP +There are a few more notations useful to the terminal user +which have not been introduced yet. +.PP +In addition to the standard output, commands also have a +.I "diagnostic output" +which is normally directed to the terminal even when the standard output +is redirected to a file or a pipe. +It is occasionally desirable to direct the diagnostic output along with +the standard output. +For instance if you want to redirect the output of a long running command +into a file and wish to have a record of any error diagnostic it produces +you can do +.DS +command >& file +.DE +The `>&' here tells the shell to route both the diagnostic output and the +standard output into `file'. +Similarly you can give the command +.DS +command |\|& lpr +.DE +to route both standard and diagnostic output through the pipe +to the line printer daemon +.I lpr.\(dd +.FS +\(dd A command of the form +.br +.ti +5 +command >&! file +.br +exists, and is used when +.I noclobber +is set and +.I file +already exists. +.FE +.PP +Finally, it is possible to use the form +.DS +command >> file +.DE +to place output at the end of an existing file.\(dg +.FS +\(dg If +.I noclobber +is set, then an error will result if +.I file +does not exist, otherwise the shell will create +.I file +if it doesn't exist. +A form +.br +.ti +5 +command >>! file +.br +makes it not be an error for file to not exist when +.I noclobber +is set. +.FE +.NH 2 +Jobs; Background, Foreground, or Suspended +.PP +When one or more commands +are typed together as a pipeline or as a sequence of commands separated by +semicolons, a single +.I job +is created by the shell consisting of these commands together as a unit. +Single commands without pipes or semicolons create the simplest jobs. +Usually, every line typed to the shell creates a job. +Some lines that create jobs (one per line) are +.DS +sort < data +ls \-s | sort \-n | head \-5 +mail harold +.DE +.PP +If the metacharacter `&' is typed +at the end of the commands, then the job is started as a +.I background +job. This means that the shell does not wait for it to complete but +immediately prompts and is ready for another command. The job runs +.I "in the background" +at the same time that normal jobs, called +.I foreground +jobs, continue to be read and executed by the shell one at a time. +Thus +.DS +du > usage & +.DE +would run the +.I du +program, which reports on the disk usage of your working directory (as well as +any directories below it), put the output into the file `usage' and return +immediately with a prompt for the next command without out waiting for +.I du +to finish. The +.I du +program would continue executing in the background +until it finished, even though you can type and execute more commands in the +mean time. +When a background +job terminates, a message is typed by the shell just before the next prompt +telling you that the job has completed. +In the following example the +.I du +job finishes sometime during the +execution of the +.I mail +command and its completion is reported just before +the prompt after the +.I mail +job is finished. +.DS +% du > usage & +[1] 503 +% mail bill +How do you know when a background job is finished? +EOT +.ta 1.75i +[1] \- Done du > usage +% +.so tabs +.DE +If the job did not terminate normally the `Done' message might say +something else like `Killed'. +If you want the +terminations of background jobs to be reported at the time they occur +(possibly interrupting the output of other foreground jobs), you can set +the +.I notify +variable. In the previous example this would mean that the +`Done' message might have come right in the middle of the message to +Bill. +Background jobs are unaffected by any signals from the keyboard like +the \s-2STOP\s0, \s-2INTERRUPT\s0, or \s-2QUIT\s0 signals mentioned earlier. +.PP +Jobs are recorded in a table inside the shell until they terminate. +In this table, the shell remembers the command names, arguments and the +.I "process numbers" +of all commands in the job as well as the working directory where the job was +started. +Each job in the table is either running +.I "in the foreground" +with the shell waiting for it to terminate, running +.I "in the background," +or +.I suspended. +Only one job can be running in the foreground at one time, but several +jobs can be suspended or running in the background at once. As each job +is started, it is assigned a small identifying +number called the +.I "job number" +which can be used later to refer to the job in the commands described below. +Job numbers remain +the same until the job terminates and then are re-used. +.PP +When a job is started in the background using `&', its number, as well +as the process numbers of all its (top level) commands, is typed by the shell +before prompting you for another command. For example, +.DS +% ls \-s | sort \-n > usage & +[2] 2034 2035 +% +.DE +runs the `ls' program with the `\-s' options, pipes this output into +the `sort' program with the `\-n' option which puts its output into the +file `usage'. +Since the `&' was at the end of the line, these two programs were started +together as a background job. After starting the job, the shell prints +the job number in brackets (2 in this case) followed by the process number +of each program started in the job. Then the shell immediates prompts for +a new command, leaving the job running simultaneously. +.PP +As mentioned in section 1.8, foreground jobs become +.I suspended +by typing ^Z +which sends a \s-2STOP\s0 signal to the currently running +foreground job. A background job can become suspended by using the +.I stop +command described below. When jobs are suspended they merely stop +any further progress until started again, either in the foreground +or the background. The shell notices when a job becomes stopped and +reports this fact, much like it reports the termination of background jobs. +For foreground jobs this looks like +.DS +% du > usage +^Z +Stopped +% +.DE +`Stopped' message is typed by the shell when it notices that the +.I du +program stopped. +For background jobs, using the +.I stop +command, it is +.DS +% sort usage & +[1] 2345 +% stop %1 +.ta 1.75i +[1] + Stopped (signal) sort usage +% +.so tabs +.DE +Suspending foreground jobs can be very useful when you need to temporarily +change what you are doing (execute other commands) and then return to +the suspended job. Also, foreground jobs can be suspended and then +continued as background jobs using the +.I bg +command, allowing you to continue other work and +stop waiting for the foreground job to finish. Thus +.DS +% du > usage +^Z +Stopped +% bg +[1] du > usage & +% +.DE +starts `du' in the foreground, stops it before it finishes, then continues +it in the background allowing more foreground commands to be executed. +This is especially helpful +when a foreground job ends up taking longer than you expected and you +wish you had started it in the background in the beginning. +.PP +All +.I "job control" +commands can take an argument that identifies a particular +job. +All job name arguments begin with the character `%', since some of the +job control commands also accept process numbers (printed by the +.I ps +command.) +The default job (when no argument is given) is called the +.I current +job and is identified by a `+' in the output of the +.I jobs +command, which shows you which jobs you have. +When only one job is stopped or running in the background (the usual case) +it is always the current job thus no argument is needed. +If a job is stopped while running in the foreground it becomes the +.I current +job and the existing current job becomes the +.I previous +job \- identified by a `\-' in the output of +.I jobs. +When the current job terminates, the previous job becomes the current job. +When given, the argument is either `%\-' (indicating +the previous job); `%#', where # is the job number; +`%pref' where pref is some unique prefix of the command name +and arguments of one of the jobs; or `%?' followed by some string found +in only one of the jobs. +.PP +The +.I jobs +command types the table of jobs, giving the job number, +commands and status (`Stopped' or `Running') of each background or +suspended job. With the `\-l' option the process numbers are also +typed. +.DS +% du > usage & +[1] 3398 +% ls \-s | sort \-n > myfile & +[2] 3405 +% mail bill +^Z +Stopped +% jobs +.ta 1.75i +[1] \(mi Running du > usage +[2] Running ls \-s | sort \-n > myfile +[3] \(pl Stopped mail bill +% fg %ls +ls \-s | sort \-n > myfile +% more myfile +.so tabs +.DE +.PP +The +.I fg +command runs a suspended or background job in the foreground. It is +used to restart a previously suspended job or change a background job +to run in the foreground (allowing signals or input from the terminal). +In the above example we used +.I fg +to change the `ls' job from the +background to the foreground since we wanted to wait for it to +finish before looking at its output file. +The +.I bg +command runs a suspended job in the background. It is usually used +after stopping the currently running foreground job with the +\s-2STOP\s0 signal. The combination of the \s-2STOP\s0 signal and the +.I bg +command changes a foreground job into a background job. +The +.I stop +command suspends a background job. +.PP +The +.I kill +command terminates a background or suspended job immediately. +In addition to jobs, it may be given process numbers as arguments, +as printed by +.I ps. +Thus, in the example above, the running +.I du +command could have been terminated by the command +.DS +% kill %1 +.ta 1.75i +[1] Terminated du > usage +% +.so tabs +.DE +.PP +The +.I notify +command (not the variable mentioned earlier) indicates that the termination +of a specific job should be +reported at the time it finishes instead of waiting for the next prompt. +.PP +If a job running in the background tries to read input from the terminal +it is automatically stopped. When such a job is then run in the +foreground, input can be given to the job. If desired, the job can +be run in the background again until it requests input again. +This is illustrated in the following sequence where the `s' command in the +text editor might take a long time. +.ID +.nf +% ed bigfile +120000 +1,$s/thisword/thatword/ +^Z +Stopped +% bg +[1] ed bigfile & +% + . . . some foreground commands +.ta 1.75i +[1] Stopped (tty input) ed bigfile +% fg +ed bigfile +w +120000 +q +% +.so tabs +.DE +So after the `s' command was issued, the `ed' job was stopped with ^Z +and then put in the background using +.I bg. +Some time later when the `s' command was finished, +.I ed +tried to read another command and was stopped because jobs +in the background cannot read from the terminal. The +.I fg +command returned the `ed' job to the foreground where it could once again +accept commands from the terminal. +.PP +The command +.DS +stty tostop +.DE +causes all background jobs run on your terminal to stop +when they are about to +write output to the terminal. This prevents messages from background +jobs from interrupting foreground job output and allows you to run +a job in the background without losing terminal output. It also +can be used for interactive programs that sometimes have long +periods without interaction. Thus each time it outputs a prompt for more +input it will stop before the prompt. It can then be run in the +foreground using +.I fg, +more input can be given and, if necessary stopped and returned to +the background. This +.I stty +command might be a good thing to put in your +.I \&.login +file if you do not like output from background jobs interrupting +your work. It also can reduce the need for redirecting the output +of background jobs if the output is not very big: +.DS +% stty tostop +% wc hugefile & +[1] 10387 +% ed text +\&. . . some time later +q +.ta 1.75i +[1] Stopped (tty output) wc hugefile +% fg wc +wc hugefile + 13371 30123 302577 +% stty \-tostop +.so tabs +.DE +Thus after some time the `wc' command, which counts the lines, words +and characters in a file, had one line of output. When it tried to +write this to the terminal it stopped. By restarting it in the +foreground we allowed it to write on the terminal exactly when we were +ready to look at its output. +Programs which attempt to change the mode of the terminal will also +block, whether or not +.I tostop +is set, when they are not in the foreground, as +it would be very unpleasant to have a background job change the state +of the terminal. +.PP +Since the +.I jobs +command only prints jobs started in the currently executing shell, +it knows nothing about background jobs started in other login sessions +or within shell files. The +.I ps +can be used in this case to find out about background jobs not started +in the current shell. +.NH 2 +Working Directories +.PP +As mentioned in section 1.6, the shell is always in a particular +.I "working directory." +The `change directory' command +.I chdir +(its +short form +.I cd +may also be used) +changes the working directory of the shell, +that is, changes the directory you +are located in. +.PP +It is useful to make a directory for each project you wish to work on +and to place all files related to that project in that directory. +The `make directory' command, +.I mkdir, +creates a new directory. +The +.I pwd +(`print working directory') command +reports the absolute pathname of the working directory of the shell, +that is, the directory you are +located in. +Thus in the example below: +.DS +% pwd +/usr/bill +% mkdir newpaper +% chdir newpaper +% pwd +/usr/bill/newpaper +% +.DE +the user has created and moved to the +directory +.I newpaper. +where, for example, he might +place a group of related files. +.PP +No matter where you have moved to in a directory hierarchy, +you can return to your `home' login directory by doing just +.DS +cd +.DE +with no arguments. +The name `..' always means the directory above the current one in +the hierarchy, thus +.DS +cd .. +.DE +changes the shell's working directory to the one directly above the +current one. +The name `..' can be used in any +pathname, thus, +.DS +cd ../programs +.DE +means +change to the directory `programs' contained in the directory +above the current one. +If you have several directories for different +projects under, say, your home directory, +this shorthand notation +permits you to switch easily between them. +.PP +The shell always remembers the pathname of its current working directory in +the variable +.I cwd. +The shell can also be requested to remember the previous directory when +you change to a new working directory. If the `push directory' command +.I pushd +is used in place of the +.I cd +command, the shell saves the name of the current working directory +on a +.I "directory stack" +before changing to the new one. +You can see this list at any time by typing the `directories' +command +.I dirs. +.ID +.nf +% pushd newpaper/references +~/newpaper/references ~ +% pushd /usr/lib/tmac +/usr/lib/tmac ~/newpaper/references ~ +% dirs +/usr/lib/tmac ~/newpaper/references ~ +% popd +~/newpaper/references ~ +% popd +~ +% +.DE +The list is printed in a horizontal line, reading left to right, +with a tilde (~) as +shorthand for your home directory\(emin this case `/usr/bill'. +The directory stack is printed whenever there is more than one +entry on it and it changes. +It is also printed by a +.I dirs +command. +.I Dirs +is usually faster and more informative than +.I pwd +since it shows the current working directory as well as any +other directories remembered in the stack. +.PP +The +.I pushd +command with no argument +alternates the current directory with the first directory in the +list. +The `pop directory' +.I popd +command without an argument returns you to the directory you were in prior to +the current one, discarding the previous current directory from the +stack (forgetting it). +Typing +.I popd +several times in a series takes you backward through the directories +you had been in (changed to) by +.I pushd +command. +There are other options to +.I pushd +and +.I popd +to manipulate the contents of the directory stack and to change +to directories not at the top of the stack; see the +.I csh +manual page for details. +.PP +Since the shell remembers the working directory in which each job +was started, it warns you when you might be confused by restarting +a job in the foreground which has a different working directory than the +current working directory of the shell. Thus if you start a background +job, then change the shell's working directory and then cause the +background job to run in the foreground, the shell warns you that the +working directory of the currently running foreground job is different +from that of the shell. +.DS +% dirs \-l +/mnt/bill +% cd myproject +% dirs +~/myproject +% ed prog.c +1143 +^Z +Stopped +% cd .. +% ls +myproject +textfile +% fg +ed prog.c (wd: ~/myproject) +.DE +This way the shell warns you when there +is an implied change of working directory, even though no cd command was +issued. In the above example the `ed' job was still in `/mnt/bill/project' +even though the shell had changed to `/mnt/bill'. +A similar warning is given when such a foreground job +terminates or is suspended (using the \s-2STOP\s0 signal) since +the return to the shell again implies a change of working directory. +.DS +% fg +ed prog.c (wd: ~/myproject) + . . . after some editing +q +(wd now: ~) +% +.DE +These messages are sometimes confusing if you use programs that change +their own working directories, since the shell only remembers which +directory a job is started in, and assumes it stays there. +The `\-l' option of +.I jobs +will type the working directory +of suspended or background jobs when it is different +from the current working directory of the shell. +.NH 2 +Useful built-in commands +.PP +We now give a few of the useful built-in commands of the shell describing +how they are used. +.PP +The +.I alias +command described above is used to assign new aliases and to show the +existing aliases. +With no arguments it prints the current aliases. +It may also be given only one argument such as +.DS +alias ls +.DE +to show the current alias for, e.g., `ls'. +.PP +The +.I echo +command prints its arguments. +It is often used in +.I "shell scripts" +or as an interactive command +to see what filename expansions will produce. +.PP +The +.I history +command will show the contents of the history list. +The numbers given with the history events can be used to reference +previous events which are difficult to reference using the +contextual mechanisms introduced above. +There is also a shell variable called +.I prompt. +By placing a `!' character in its value the shell will there substitute +the number of the current command in the history list. +You can use this number to refer to this command in a history substitution. +Thus you could +.DS +set prompt=\'\e! % \' +.DE +Note that the `!' character had to be +.I escaped +here even within `\'' characters. +.PP +The +.I limit +command is used to restrict use of resources. +With no arguments it prints the current limitations: +.DS +.ta 1i +cputime unlimited +filesize unlimited +datasize 5616 kbytes +stacksize 512 kbytes +coredumpsize unlimited +.so tabs +.DE +Limits can be set, e.g.: +.DS +limit coredumpsize 128k +.DE +Most reasonable units abbreviations will work; see the +.I csh +manual page for more details. +.PP +The +.I logout +command can be used to terminate a login shell which has +.I ignoreeof +set. +.PP +The +.I rehash +command causes the shell to recompute a table of where commands are +located. This is necessary if you add a command to a directory +in the current shell's search path and wish the shell to find it, +since otherwise the hashing algorithm may tell the shell that the +command wasn't in that directory when the hash table was computed. +.PP +The +.I repeat +command can be used to repeat a command several times. +Thus to make 5 copies of the file +.I one +in the file +.I five +you could do +.DS +repeat 5 cat one >> five +.DE +.PP +The +.I setenv +command can be used +to set variables in the environment. +Thus +.DS +setenv TERM adm3a +.DE +will set the value of the environment variable \s-2TERM\s0 +to +`adm3a'. +A user program +.I printenv +exists which will print out the environment. +It might then show: +.DS +% printenv +HOME=/usr/bill +SHELL=/bin/csh +PATH=:/usr/ucb:/bin:/usr/bin:/usr/local +TERM=adm3a +USER=bill +% +.DE +.PP +The +.I source +command can be used to force the current shell to read commands from +a file. +Thus +.DS +source .cshrc +.DE +can be used after editing in a change to the +.I \&.cshrc +file which you wish to take effect right away. +.PP +The +.I time +command can be used to cause a command to be timed no matter how much +\s-2CPU\s0 time it takes. +Thus +.DS +% time cp /etc/rc /usr/bill/rc +0.0u 0.1s 0:01 8% 2+1k 3+2io 1pf+0w +% time wc /etc/rc /usr/bill/rc + 52 178 1347 /etc/rc + 52 178 1347 /usr/bill/rc + 104 356 2694 total +0.1u 0.1s 0:00 13% 3+3k 5+3io 7pf+0w +% +.DE +indicates that the +.I cp +command used a negligible amount of user time (u) +and about 1/10th of a system time (s); the elapsed time was 1 second (0:01), +there was an average memory usage of 2k bytes of program space and 1k +bytes of data space over the cpu time involved (2+1k); the program +did three disk reads and two disk writes (3+2io), and took one page fault +and was not swapped (1pf+0w). +The word count command +.I wc +on the other hand used 0.1 seconds of user time and 0.1 seconds of system +time in less than a second of elapsed time. +The percentage `13%' indicates that over the period when it was active +the command `wc' used an average of 13 percent of the available \s-2CPU\s0 +cycles of the machine. +.PP +The +.I unalias +and +.I unset +commands can be used +to remove aliases and variable definitions from the shell, and +.I unsetenv +removes variables from the environment. +.NH 2 +What else? +.PP +This concludes the basic discussion of the shell for terminal users. +There are more features of the shell to be discussed here, and all +features of the shell are discussed in its manual pages. +One useful feature which is discussed later is the +.I foreach +built-in command which can be used to run the same command +sequence with a number of different arguments. +.PP +If you intend to use \s-2UNIX\s0 a lot you you should look through +the rest of this document and the csh manual pages (section1) to become familiar +with the other facilities which are available to you. +.bp diff --git a/static/netbsd/man2/delayedkeys.conf.2 b/static/netbsd/man2/delayedkeys.conf.2 new file mode 100644 index 00000000..9ac3524b --- /dev/null +++ b/static/netbsd/man2/delayedkeys.conf.2 @@ -0,0 +1,21 @@ +.\" $NetBSD: delayedkeys.conf.2,v 1.2 2025/01/26 16:24:51 christos Exp $ +.\" +/* + * Copyright (C) Internet Systems Consortium, Inc.

it is a new reference to the same +underlying system object. +The object in question does not distinguish between the descriptors +referencing it in any way. +Thus for files, +.Xr read 2 , +.Xr write 2 +and +.Xr lseek 2 +calls all move a single shared seek position. +Similarly, all object modes, settings, properties, and behavior other +than the close-on-exec & close-on-fork flags are shared between references. +This includes the setting of append mode, non-blocking I/O actions, +asynchronous I/O operations in progress, socket options, and so forth. +The close-on-exec & close-on-fork flags, however, are a property of the +descriptor rather than the object and can be set independently for each +reference. +.Pp +To get an independent handle with its own seek position and settings, +an additional +.Xr open 2 +call must be issued. +(This is not generally possible for pipes and sockets.) +.Pp +The +.Fn dup +call chooses the new descriptor: it is the lowest-numbered descriptor +not currently in use. +The +.Fn dup2 +and +.Fn dup3 +calls allow the caller to choose the new descriptor by passing +.Fa newfd , +which must be within the range of valid descriptors. +If +.Fa newfd +is the same as +.Fa oldfd , +in +.Fn dup2 +the call has no effect, +whereas it is an error in +.Fn dup3 . +Otherwise, if +.Fa newfd +is already in use, it is closed as if +.Xr close 2 +had been called. +.Pp +File descriptors are small non-negative integers that index into the +per-process file table. +Values 0, 1, and 2 have the special property that they are treated as +standard input, standard output, and standard error respectively. +(The constants +.Dv STDIN_FILENO , +.Dv STDOUT_FILENO , +and +.Dv STDERR_FILENO +are provided as symbolic forms for these values.) +The maximum value for a file descriptor is one less than the file +table size. +The file table size can be interrogated with +.Xr getdtablesize 3 +and can to some extent be adjusted with +.Xr setrlimit 2 . +.Pp +The +.Fn dup3 +call fails and returns +.Er EINVAL +if the numeric value in the +.Ar oldfd +argument is equal to the one in the +.Ar newfd +argument. +It also includes an additional +.Fa flags +argument supporting a subset of the +.Xr open 2 +flags: +.Bl -tag -width O_NOSIGPIPE -offset indent +.It Dv O_CLOEXEC +Set the close-on-exec flag on +.Fa newfd . +.It Dv O_CLOFORK +Set the close-on-fork flag on +.Fa newfd . +.It Dv O_NONBLOCK +Sets non-blocking I/O. +.It Dv O_NOSIGPIPE +For pipes and sockets, do not raise +.Dv SIGPIPE +when a write is made to a broken pipe. +Instead, the write will fail with +.Er EPIPE . +.El +.Pp +As described above, only the close-on-exec and close-on-fork flags are +per-file-descriptor, so passing any of the other +.Fa flags +will affect +both +.Fa oldfd +and +.Fa newfd . +These settings are, however, applied atomically along with the rest of +the +.Fn dup3 +operation. +.Pp +In the case of +.Fn dup +and +.Fn dup2 +the close-on-exec and close-on-fork flags on the new file descriptor are +always left unset +and all the modes and settings of the underlying object are left unchanged. +.Pp +Functionality similar to +.Fn dup +with slightly different semantics is also available via +.Xr fcntl 2 . +.Sh RETURN VALUES +When successful, these calls return the new file descriptor value. +In the case of +.Fn dup2 +and +.Fn dup3 +this is always the same as +.Fa newfd . +If an error occurs, the value \-1 is returned and +.Va errno +is set to indicate what happened. +.Sh EXAMPLES +A common use for these functions is to set up a pipe as the standard +input or standard output of a subprocess. +That is done approximately as follows (with error handling omitted for +clarity): +.Bd -literal -offset indent +#include <unistd.h> + +int fds[2];

+.Fn fcntl +provides for control over descriptors. +The argument +.Fa fd +is a descriptor to be operated on by +.Fa cmd +as described below. +The third parameter is called +.Fa arg +and is technically

+.Pp +.Bl -bullet -compact -offset 4n +.It +Lowest numbered available descriptor greater than or equal to +.Fa arg , +which is interpreted as an int. +.It +Same object references as the original descriptor. +.It +New descriptor shares the same file offset if the object +was a file. +.It +Same access mode (read, write or read/write). +.It +Same file status flags (i.e., both file descriptors +share the same file status flags). +.It +The close-on-exec flag associated with the new file descriptor +is cleared to allow the file descriptor to remain open across +.Xr execve 2 +system calls. +.It +The close-on-fork flag +.Dv FD_CLOFORK +associated with the new file descriptor is cleared, +so the file descriptor will remain open across +.Xr fork 2 +system calls. +.El +.It Dv F_DUPFD_CLOEXEC +Same as +.Dv F_DUPFD , +but sets the close-on-exec property on the file descriptor created. +.It Dv F_DUPFD_CLOFORK +Same as +.Dv F_DUPFD , +but sets the close-on-fork property on the file descriptor created. +.It Dv F_DUPFD_CLOBOTH +Same as +.Dv F_DUPFD , +but sets both the close-on-exec and close-on-fork properties on the file +descriptor created. +.It Dv F_GETFD +Get the flags associated with the file descriptor +.Fa fd +.Fa ( arg +is ignored). +If the returned value ANDed with +.Dv FD_CLOEXEC +is 0, +the file will remain open across +.Fn exec , +otherwise the file will be closed upon execution of +.Fn exec . +If the returned value ANDed with +.Dv FD_CLOFORK +is not 0, +the file will be closed upon execution of the +.Fn fork +family of system calls. +.It Dv F_SETFD +Set flags associated with +.Fa fd . +The available flags, passed as +.Fa arg +(treated as an integer), are +.Dv FD_CLOEXEC +and +.Dv FD_CLOFORK . +.It Dv F_GETFL +Get descriptor status flags, as described below +.Fa ( arg +is ignored). +.It Dv F_SETFL +Set descriptor status flags to +.Fa arg , +which is interpreted as an int. +.It Dv F_GETOWN +Get the process ID or process group +currently receiving +.Dv SIGIO +and +.Dv SIGURG +signals; process groups are returned +as negative values +.Fa ( arg +is ignored). +.It Dv F_SETOWN +Set the process or process group +to receive +.Dv SIGIO +and +.Dv SIGURG +signals; +process groups are specified by supplying +.Fa arg +as negative, otherwise +.Fa arg +is interpreted as a process ID. +The argument +.Fa arg +is interpreted as an int. +.It Dv F_CLOSEM +Close all file descriptors greater than or equal to +.Fa fd , +.Fa ( arg +is ignored). +.It Dv F_MAXFD +Return the maximum file descriptor number currently open by the process. +.Fa ( arg +is ignored). +.It Dv F_GETNOSIGPIPE +Return 1 if the +.Dv O_NOSIGPIPE +flag is set in the file descriptor, otherwise 0 +.Fa ( arg +is ignored). +.It Dv F_SETNOSIGPIPE +If +.Fa arg +is 0, clear the +.Dv O_NOSIGPIPE +status in the file descriptor, otherwise set it. +.It Dv F_GETPATH +Place a pathname corresponding to +.Fa fd +in the buffer pointed to by +.Fa arg . +.Fa arg +should be pointing to a buffer of at least +.Dv MAXPATHLEN +bytes. +.It Dv F_ADD_SEALS +Add seals specified in +.Fa arg +to +.Fa fd +to restrict possible operations on +.Fa fd +as described below. +Like flags, multiple seals can be specified at once. +Additionally, specifying seals that are already associated with +.Fa fd +is a no-op. +.It Dv F_GET_SEALS +Get the seals currently associated with +.Fa fd +as described below +.Fa ( arg +is ignored). +.El +.Pp +The set of valid flags for the +.Dv F_GETFL +and +.Dv F_SETFL +flags are as follows: +.Dv O_APPEND , +.Dv O_ASYNC , +.Dv O_SYNC , +.Dv O_NONBLOCK , +.Dv O_DSYNC , +.Dv O_RSYNC , +.Dv O_ALT_IO , +.Dv O_DIRECT , +.Dv O_NOSIGPIPE . +These flags are described in +.Xr open 2 . +.Pp +Several commands are available for doing advisory file locking; +they all operate on the following structure: +.Bd -literal +struct flock { + off_t l_start; /* starting offset */ + off_t l_len; /* len = 0 means until end of file */ + pid_t l_pid; /* lock owner */ + short l_type; /* lock type: read/write, etc. */ + short l_whence; /* type of l_start */ +}; +.Ed +.Pp +The commands available for advisory record locking are as follows: +.Bl -tag -width F_SETLKWX +.It Dv F_GETLK +Get the first lock that blocks the lock description pointed to by the +third argument, +.Fa arg , +taken as a pointer to a +.Fa "struct flock" +(see above). +The information retrieved overwrites the information passed to +.Nm +in the +.Fa flock +structure. +If no lock is found that would prevent this lock from being created, +the structure is left unchanged by this function call except for the +lock type +.Fa l_type , +which is set to +.Dv F_UNLCK . +.It Dv F_SETLK +Set or clear a file segment lock according to the lock description +pointed to by the third argument, +.Fa arg , +taken as a pointer to a +.Fa "struct flock" +(see above). +As specified by the value of +.Fa l_type , +.Dv F_SETLK +is used to establish shared (or read) locks +.Pq Dv F_RDLCK +or exclusive (or write) locks, +.Pq Dv F_WRLCK , +as well as remove either type of lock +.Pq Dv F_UNLCK . +If a shared or exclusive lock cannot be set, +.Nm +returns immediately with +.Er EAGAIN . +.It Dv F_SETLKW +This command is the same as +.Dv F_SETLK +except that if a shared or exclusive lock is blocked by other locks, +the process waits until the request can be satisfied. +If a signal that is to be caught is received while +.Nm +is waiting for a region, the +.Nm +will be interrupted if the signal handler has not specified the +.Dv SA_RESTART +(see +.Xr sigaction 2 ) . +.El +.Pp +When a shared lock has been set on a segment of a file, +other processes can set shared locks on that segment +or a portion of it. +A shared lock prevents any other process from setting an exclusive +lock on any portion of the protected area. +A request for a shared lock fails if the file descriptor was not +opened with read access. +.Pp +An exclusive lock prevents any other process from setting a shared lock or +an exclusive lock on any portion of the protected area. +A request for an exclusive lock fails if the file was not +opened with write access. +.Pp +The value of +.Fa l_whence +is +.Dv SEEK_SET , +.Dv SEEK_CUR , +or +.Dv SEEK_END +to indicate that the relative offset, +.Fa l_start +bytes, will be measured from the start of the file, +current position, or end of the file, respectively. +The value of +.Fa l_len +is the number of consecutive bytes to be locked. +If +.Fa l_len +is negative, the result is undefined. +The +.Fa l_pid +field is only used with +.Dv F_GETLK +to return the process ID of the process holding a blocking lock. +After a successful +.Dv F_GETLK +request, the value of +.Fa l_whence +is +.Dv SEEK_SET . +.Pp +Locks may start and extend beyond the current end of a file, +but may not start or extend before the beginning of the file. +A lock is set to extend to the largest possible value of the +file offset for that file if +.Fa l_len +is set to zero. +If +.Fa l_whence +and +.Fa l_start +point to the beginning of the file, and +.Fa l_len +is zero, the entire file is locked. +If an application wishes only to do entire file locking, the +.Xr flock 2 +system call is much more efficient. +.Pp +There is at most one type of lock set for each byte in the file. +Before a successful return from an +.Dv F_SETLK +or an +.Dv F_SETLKW +request when the calling process has previously existing locks +on bytes in the region specified by the request, +the previous lock type for each byte in the specified +region is replaced by the new lock type. +As specified above under the descriptions +of shared locks and exclusive locks, an +.Dv F_SETLK +or an +.Dv F_SETLKW +request fails or blocks respectively when another process has existing +locks on bytes in the specified region and the type of any of those +locks conflicts with the type specified in the request. +.Pp +Possible seals are: +.Bl -tag -width F_SEAL_FUTURE_WRITE +.It Dv F_SEAL_SEAL +Prevent any further seals from being added to +.Fa fd . +.It Dv F_SEAL_SHRINK +Prevent the size of +.Fa fd +from decreasing. +.It Dv F_SEAL_GROW +Prevent the size of +.Fa fd +from increasing. +.It Dv F_SEAL_WRITE +Prevent any write operations to +.Fa fd . +.Dv F_SEAL_WRITE +cannot be applied if +.Fa fd +has any memory mappings. +.It Dv F_SEAL_FUTURE_WRITE +Like +.Dv F_SEAL_WRITE +but allow any current memory mappings of +.Fa fd +to remain open, including those with +.Dv PROT_WRITE . +.El +.Sh NOTES +For +.Dv F_GETPATH : +.Bl -bullet -compact +.It +For vnodes, functionality is implemented using the reverse +.Xr namei 9 +cache. +The implications of this are +.Bl -bullet -compact +.It +For hard links where the file descriptor can resolve to multiple pathnames, +the first entry found in the cache is returned. +.It +.Dv F_GETPATH +may fail if the corresponding entry has been evicted from the LRU +.Xr namei 9 +cache and return +.Er ENOENT . +.El +.It +For a file descriptor created by +.Xr memfd_create 2 , +the name provided at +.Fa fd +creation, with the prefix +.Dq memfd: +is used. +.It +Other types of file descriptors are not handled, as well as symbolic +links since there is currently no way to obtain a file descriptor +pointing to a symbolic link. +.El +.Sh RETURN VALUES +Upon successful completion, the value returned depends on +.Fa cmd +as follows: +.Bl -tag -width F_GET_SEALS -offset indent +.It Dv F_DUPFD +A new file descriptor. +.It Dv F_GETFD +Value of flag (one or both of the bits +.Dv FD_CLOEXEC +and +.Dv FD_CLOFORK ) . +.It Dv F_GETFL +Value of flags. +.It Dv F_GETOWN +Value of file descriptor owner. +.It Dv F_MAXFD +Value of the highest file descriptor open by the process. +.It Dv F_GET_SEALS +Value of the seals currently associated with +.Fa fd . +.It other +Value other than \-1. +.El +.Pp +Otherwise, a value of \-1 is returned and +.Va errno +is set to indicate the error. +.Sh COMPATIBILITY +This interface follows the completely stupid semantics of +.At V +and +.St -p1003.1-88 +that require that all locks associated with a file for a given process are +removed when \fIany\fP file descriptor for that file is closed by that process. +This semantic means that applications must be aware of any files that +a subroutine library may access. +For example if an application for updating the password file locks the +password file database while making the update, and then calls +.Xr getpwnam 3 +to retrieve a record, +the lock will be lost because +.Xr getpwnam 3 +opens, reads, and closes the password database. +The database close will release all locks that the process has +associated with the database, even if the library routine never +requested a lock on the database. +.Pp +Another minor semantic problem with this interface is that +locks are not inherited by a child process created using the +.Xr fork 2 +function. +The +.Xr flock 2 +interface has much more rational last close semantics and +allows locks to be inherited by child processes. +Calling +.Xr flock 2 +is recommended for applications that want to ensure the integrity +of their locks when using library routines or wish to pass locks +to their children. +Note that +.Xr flock 2 +and +.Nm +locks may be safely used concurrently. +.Pp +All locks associated with a file for a given process are +removed when the process terminates. +.Pp +A potential for deadlock occurs if a process controlling a locked region +is put to sleep by attempting to lock the locked region of another process. +This implementation detects that sleeping until a locked region is unlocked +would cause a deadlock and fails with an +.Er EDEADLK +error. +.Sh ERRORS +.Fn fcntl +will fail if: +.Bl -tag -width Er +.It Bq Er EACCES +The argument +.Fa cmd +is +.Dv F_GETPATH +and read

it will then be accessible with +.Xr recv 2 +or +.Xr read 2 +calls without the +.Dv MSG_OOB +flag. +Some protocols always behave as if this option is set. +.Dv SO_SNDBUF +and +.Dv SO_RCVBUF +are options to adjust the normal +buffer sizes allocated for output and input buffers, respectively. +The buffer size may be increased for high-volume connections, +or may be decreased to limit the possible backlog of incoming data. +The system places an absolute limit on these values. +.Pp +.Dv SO_SNDLOWAT +is an option to set the minimum count for output operations. +Most output operations process all of the data supplied +by the call, delivering data to the protocol for transmission +and blocking as necessary for flow control. +Nonblocking output operations will process as much data as permitted +subject to flow control without blocking, but will process no data +if flow control does not allow the smaller of the low water mark value +or the entire request to be processed. +A +.Xr select 2 +or +.Xr poll 2 +operation testing the ability to write to a socket will return true +only if the low water mark amount could be processed. +The default value for +.Dv SO_SNDLOWAT +is set to a convenient size for network efficiency, often 1024. +.Dv SO_RCVLOWAT +is an option to set the minimum count for input operations. +In general, receive calls will block until any (non-zero) amount of data +is received, then return with the smaller of the amount available or the amount +requested. +The default value for +.Dv SO_RCVLOWAT +is 1. +If +.Dv SO_RCVLOWAT +is set to a larger value, blocking receive calls normally +wait until they have received the smaller of the low water mark value +or the requested amount. +Receive calls may still return less than the low water mark if an error +occurs, a signal is caught, or the type of data next in the receive queue +is different than that returned. +.Pp +.Dv SO_SNDTIMEO +is an option to set a timeout value for output operations. +It accepts a +.Fa struct timeval +parameter with the number of seconds and microseconds +used to limit waits for output operations to complete. +If a send operation has blocked for this much time, +it returns with a partial count +or with the error +.Er EAGAIN +if no data were sent. +In the current implementation, this timer is restarted each time additional +data are delivered to the protocol, +implying that the limit applies to output portions ranging in size +from the low water mark to the high water mark for output. +.Dv SO_RCVTIMEO +is an option to set a timeout value for input operations. +It accepts a +.Fa struct timeval +parameter with the number of seconds and microseconds +used to limit waits for input operations to complete. +In the current implementation, this timer is restarted each time additional +data are received by the protocol, +and thus the limit is in effect an inactivity timer. +If a receive operation has been blocked for this much time without +receiving additional data, it returns with a short count +or with the error +.Er EAGAIN +if no data were received. +.Pp +If the +.Dv SO_TIMESTAMP +option is enabled on a +.Dv SOCK_DGRAM +socket, the +.Xr recvmsg 2 +call will return a timestamp corresponding to when the datagram was +received. +The msg_control field in the msghdr structure points to a buffer +that contains a cmsghdr structure followed by a struct timeval. +The cmsghdr fields have the following values: +.Bd -literal +cmsg_len = sizeof(struct timeval) +cmsg_level = SOL_SOCKET +cmsg_type = SCM_TIMESTAMP +.Ed +.Pp +.Dv SO_ACCEPTFILTER +places an +.Xr accept_filter 9 +on the socket, which will filter incoming connections on a listening +socket before being presented for +.Xr accept 2 . +The +.Fn setsockopt +system call will fail if the socket already has a filter set, and +.Xr listen 2 +must be called on the socket before trying to install a filter. +The +.Fa optval +argument +should point to a +.Fa struct accept_filter_arg +that will select and configure the +.Xr accept_filter 9 , +defined as follows: +.Bd -literal +struct accept_filter_arg { + char af_name[16]; + char af_arg[256-16]; +}; +.Ed +.Lp +The +.Fa af_name +argument should be filled with the name of the accept filter +that the application wishes to place on the listening socket. +The optional argument +.Fa af_arg +can be passed to the accept filter specified by +.Fa af_name +to provide additional configuration options at attach time. +Passing in an +.Fa optval +of +.Dv NULL +will remove the filter. +.Pp +Finally, +.Dv SO_TYPE +and +.Dv SO_ERROR +are options used only with +.Fn getsockopt +or +.Fn getsockopt2 . +.Dv SO_TYPE +returns the type of the socket, such as +.Dv SOCK_STREAM ;

method of notifying the user when an event +happens or a condition holds, based on the results of small +pieces of kernel code termed filters. +A kevent is identified by the (ident, filter) pair; there may only +be one unique kevent per kqueue. +.Pp +The filter is executed upon the initial registration of a kevent +in order to detect whether a preexisting condition is present, and is also +executed whenever an event is passed to the filter for evaluation. +If the filter determines that the condition should be reported, +then the kevent is placed on the kqueue for the user to retrieve. +.Pp +The filter is also run when the user attempts to retrieve the kevent +from the kqueue. +If the filter indicates that the condition that triggered +the event no longer holds, the kevent is removed from the kqueue and +is not returned. +.Pp +Multiple events which trigger the filter do not result in multiple +kevents being placed on the kqueue; instead, the filter will aggregate +the events into a single struct kevent. +Calling +.Xr close 2 +on a file descriptor will remove any kevents that reference the descriptor. +.Pp +The +.Fn kqueue +system call +creates a new kernel event queue and returns a descriptor. +.Pp +The +.Fn kqueue1 +system call also allows to set the following +.Fa flags +on the returned file descriptor: +.Bl -column O_NONBLOCK -offset indent +.It Dv O_CLOEXEC +Set the close on exec property. +.It Dv O_NONBLOCK +Set non-blocking I/O. +.It Dv O_NOSIGPIPE +Return +.Er EPIPE +instead of raising +.Dv SIGPIPE . +.El +.Pp +The queue is not inherited by a child created with +.Xr fork 2 . +.\" However, if +.\" .Xr rfork 2 +.\" is called without the +.\" .Dv RFFDG +.\" flag, then the descriptor table is shared, +.\" which will allow sharing of the kqueue between two processes. +.Pp +The +.Fn kevent +system call +is used to register events with the queue, and return any pending +events to the user. +The +.Fa changelist +argument +is a pointer to an array of +.Va kevent +structures, as defined in +.In sys/event.h . +All changes contained in the +.Fa changelist +are applied before any pending events are read from the queue. +The +.Fa nchanges +argument +gives the size of +.Fa changelist . +The +.Fa eventlist +argument +is a pointer to an array of kevent structures. +The +.Fa nevents +argument +determines the size of +.Fa eventlist . +When +.Fa nevents +is zero, +.Fn kevent +will return immediately even if there is a +.Fa timeout +specified unlike +.Xr select 2 . +If +.Fa timeout +is a +.No non- Ns Dv NULL +pointer, it specifies a maximum interval to wait +for an event, which will be interpreted as a +.Li struct timespec . +If +.Fa timeout +is a +.Dv NULL +pointer, +.Fn kevent +waits indefinitely. +To effect a poll, the +.Fa timeout +argument should be +.No non- Ns Dv NULL , +pointing to a zero-valued +.Xr timespec 3 +structure. +The same array may be used for the +.Fa changelist +and +.Fa eventlist . +.Pp +The +.Fn EV_SET +macro is provided for ease of initializing a kevent structure. +This macro does not evaluate its parameters multiple times. +.Pp +The +.Va kevent +structure is defined as: +.Bd -literal +struct kevent { + uintptr_t ident; /* identifier for this event */ + uint32_t filter; /* filter for event */ + uint32_t flags; /* action flags for kqueue */ + uint32_t fflags; /* filter flag value */ + int64_t data; /* filter data value */ + void *udata; /* opaque user data identifier */ + uint64_t ext[4]; /* extensions */ +}; +.Ed +.Pp +The fields of +.Fa struct kevent +are: +.Bl -tag -width "Fa filter" -offset indent +.It ident +Value used to identify this event. +The exact interpretation is determined by the attached filter, +but often is a file descriptor. +.It Fa filter +Identifies the kernel filter used to process this event. +There are pre-defined system filters (which are described below), and +other filters may be added by kernel subsystems as necessary. +.It Fa flags +Actions to perform on the event. +.It Fa fflags +Filter-specific flags. +.It Fa data +Filter-specific data value. +.It Fa udata +Opaque user-defined value passed through the kernel unchanged. +.It Fa ext +Extended data passed to and from kernel. +The +.Fa ext[0] +and +.Fa ext[1] +members use is defined by the filter. +If the filter does not use them, the members are copied unchanged. +The +.Fa ext[2] +and +.Fa ext[3] +members are always passed through the kernel as-is, +making additional context available to application. +.El +.Pp +The +.Va flags +field can contain the following values: +.Bl -tag -width XXXEV_ONESHOT -offset indent +.It Dv EV_ADD +Adds the event to the kqueue. +Re-adding an existing event will modify the parameters of the original +event, and not result in a duplicate entry. +Adding an event automatically enables it, +unless overridden by the EV_DISABLE flag. +.It Dv EV_ENABLE +Permit +.Fn kevent +to return the event if it is triggered. +.It Dv EV_DISABLE +Disable the event so +.Fn kevent +will not return it. +The filter itself is not disabled. +.It Dv EV_DISPATCH +Disable the event source immediately after delivery of an event. +See +.Dv EV_DISABLE +above. +.It Dv EV_DELETE +Removes the event from the kqueue. +Events which are attached to file descriptors are automatically deleted +on the last close of the descriptor. +.It Dv EV_RECEIPT +This flag is useful for making bulk changes to a kqueue without draining +any pending events. +When passed as input, it forces +.Dv EV_ERROR +to always be returned. +When a filter is successfully added the +.Va data +field will be zero. +Note that if this flag is encountered and there is no remaining space in +.Fa eventlist +to hold the +.Dv EV_ERROR +event, then subsequent changes will not get processed. +.It Dv EV_ONESHOT +Causes the event to return only the first occurrence of the filter +being triggered. +After the user retrieves the event from the kqueue, it is deleted. +.It Dv EV_CLEAR +After the event is retrieved by the user, its state is reset. +This is useful for filters which report state transitions +instead of the current state. +Note that some filters may automatically set this flag internally. +.It Dv EV_EOF +Filters may set this flag to indicate filter-specific EOF condition. +.It Dv EV_ERROR +See +.Sx RETURN VALUES +below. +.El +.Ss Filters +Filters are identified by a number. +There are two types of filters; pre-defined filters which +are described below, and third-party filters that may be added with +.Xr kfilter_register 9 +by kernel sub-systems, third-party device drivers, or loadable +kernel modules. +.Pp +As a third-party filter is referenced by a well-known name instead +of a statically assigned number, two +.Xr ioctl 2 Ns s +are supported on the file descriptor returned by +.Fn kqueue +to map a filter name to a filter number, and vice-versa (passing +arguments in a structure described below): +.Bl -tag -width KFILTER_BYFILTER -offset indent +.It Dv KFILTER_BYFILTER +Map +.Va filter +to +.Va name , +which is of size +.Va len . +.It Dv KFILTER_BYNAME +Map +.Va name +to +.Va filter . +.Va len +is ignored. +.El +.Pp +The following structure is used to pass arguments in and out of the +.Xr ioctl 2 : +.Bd -literal -offset indent +struct kfilter_mapping { + char *name; /* name to lookup or return */ + size_t len; /* length of name */ + uint32_t filter; /* filter to lookup or return */ +}; +.Ed +.Pp +The predefined system filters are listed below. +Arguments may be passed to and from the filter via the +.Va fflags +and +.Va data +fields in the kevent structure. +.Pp +The predefined system filters are: +.Bl -tag -width EVFILT_SIGNAL +.It Dv EVFILT_READ +Takes a descriptor as the identifier, and returns whenever +there is data available to read. +The behavior of the filter is slightly different depending +on the descriptor type. +.Bl -tag -width 2n +.It Sockets +Sockets which have previously been passed to +.Xr listen 2 +return when there is an incoming connection pending. +.Va data +contains the size of the listen backlog (i.e., the number of +connections ready to be accepted with +.Xr accept 2 . ) +.Pp +Other socket descriptors return when there is data to be read, +subject to the +.Dv SO_RCVLOWAT +value of the socket buffer. +This may be overridden with a per-filter low water mark at the +time the filter is added by setting the +NOTE_LOWAT +flag in +.Va fflags , +and specifying the new low water mark in +.Va data . +On return, +.Va data +contains the number of bytes in the socket buffer. +.Pp +If the read direction of the socket has shutdown, then the filter +also sets EV_EOF in +.Va flags , +and returns the socket error (if any) in +.Va fflags . +It is possible for EOF to be returned (indicating the connection is gone) +while there is still data pending in the socket buffer. +.It Vnodes +Returns when the file pointer is not at the end of file. +.Va data +contains the offset from current position to end of file, +and may be negative. +.\" .Pp +.\" This behavior is different from +.\" .Xr poll 2 , +.\" where read events are triggered for regular files unconditionally. +.\" This event can be triggered unconditionally by setting the +.\" .Dv NOTE_FILE_POLL +.\" flag in +.\" .Va fflags . +.It "Fifos, Pipes" +Returns when there is data to read; +.Va data +contains the number of bytes available. +.Pp +When the last writer disconnects, the filter will set EV_EOF in +.Va flags . +This may be cleared by passing in EV_CLEAR, at which point the +filter will resume waiting for data to become available before +returning. +.It "BPF devices" +Returns when the BPF buffer is full, the BPF timeout has expired, or +when the BPF has +.Dq immediate mode +enabled and there is any data to read; +.Va data +contains the number of bytes available. +.El +.It Dv EVFILT_WRITE +Takes a descriptor as the identifier, and returns whenever +it is possible to write to the descriptor. +For sockets, pipes, fifos, and ttys, +.Va data +will contain the amount of space remaining in the write buffer. +The filter will set EV_EOF when the reader disconnects, and for +the fifo case, this may be cleared by use of EV_CLEAR. +Note that this filter is not supported for vnodes. +.Pp +For sockets, the low water mark and socket error handling is +identical to the EVFILT_READ case. +.It Dv EVFILT_EMPTY +Takes a descriptor as the identifier, and returns whenever +there is no remaining data in the write buffer. +This is currently implemented only for sockets. +It's primary purpose is to provide visibility to an application that all +previously written data has been acknowledged by the receiver at the TCP +layer. +.It Dv EVFILT_AIO +This is not implemented in +.Nx . +.ig +The sigevent portion of the AIO request is filled in, with +.Va sigev_notify_kqueue +containing the descriptor of the kqueue that the event should +be attached to, +.Va sigev_value +containing the udata value, and +.Va sigev_notify +set to SIGEV_EVENT. +When the aio_* function is called, the event will be registered +with the specified kqueue, and the +.Va ident +argument set to the +.Fa struct aiocb +returned by the aio_* function. +The filter returns under the same conditions as aio_error. +.Pp +Alternatively, a kevent structure may be initialized, with +.Va ident +containing the descriptor of the kqueue, and the +address of the kevent structure placed in the +.Va aio_lio_opcode +field of the AIO request. +However, this approach will not work on +architectures with 64-bit pointers, and should be considered deprecated. +.. +.It Dv EVFILT_VNODE +Takes a file descriptor as the identifier and the events to watch for in +.Va fflags , +and returns when one or more of the requested events occurs on the descriptor. +The events to monitor are: +.Bl -tag -width NOTE_CLOSE_WRITE +.It Dv NOTE_ATTRIB +The file referenced by the descriptor had its attributes changed. +.It Dv NOTE_CLOSE +A file descriptor without write access referencing the file was closed. +.It Dv NOTE_CLOSE_WRITE +A file descriptor with write access referencing the file was closed. +.It Dv NOTE_DELETE +.Xr unlink 2 +was called on the file referenced by the descriptor. +.It Dv NOTE_EXTEND +The file referenced by the descriptor was extended. +.It Dv NOTE_LINK +The link count on the file changed. +.It Dv NOTE_OPEN +The file referenced by the descriptor was opened. +.It Dv NOTE_READ +A read occurred on the file referenced by the descriptor. +.It Dv NOTE_RENAME +The file referenced by the descriptor was renamed. +.It Dv NOTE_REVOKE +Access to the file was revoked via +.Xr revoke 2 +or the underlying file system was unmounted. +.It Dv NOTE_WRITE +A write occurred on the file referenced by the descriptor. +.El +.Pp +On return, +.Va fflags +contains the events which triggered the filter. +.It Dv EVFILT_PROC +Takes the process ID to monitor as the identifier and the events to watch for +in +.Va fflags , +and returns when the process performs one or more of the requested events. +If a process can normally see another process, it can attach an event to it. +The events to monitor are: +.Bl -tag -width XXNOTE_TRACKERR +.It Dv NOTE_EXIT +The process has exited. +The exit code of the process is stored in +.Va data . +.It Dv NOTE_FORK +The process has called +.Xr fork 2 . +.It Dv NOTE_EXEC +The process has executed a new process via +.Xr execve 2 +or similar call. +.It Dv NOTE_TRACK +Follow a process across +.Xr fork 2 +calls. +The parent process will return with NOTE_TRACK set in the +.Va fflags +field, while the child process will return with NOTE_CHILD set in +.Va fflags +and the parent PID in +.Va data . +.It Dv NOTE_TRACKERR +This flag is returned if the system was unable to attach an event to +the child process, usually due to resource limitations. +.El +.Pp +On return, +.Va fflags +contains the events which triggered the filter. +.It Dv EVFILT_SIGNAL +Takes the signal number to monitor as the identifier and returns +when the given signal is delivered to the current process. +This coexists with the +.Xr signal 3 +and +.Xr sigaction 2 +facilities, and has a lower precedence. +The filter will record +all attempts to deliver a signal to a process, even if the signal has +been marked as SIG_IGN. +Event notification happens after normal signal delivery processing. +.Va data +returns the number of times the signal has occurred since the last call to +.Fn kevent . +This filter automatically sets the EV_CLEAR flag internally. +.It Dv EVFILT_TIMER +Establishes an arbitrary timer identified by +.Va ident . +When adding a timer, +.Va data +specifies the timeout period in units described below, or, if +.Dv NOTE_ABSTIME +is set in +.Va fflags , +specifies the absolute time at which the timer should fire. +The timer will repeat unless +.Dv EV_ONESHOT +is set in +.Va flags +or +.Dv NOTE_ABSTIME +is set in +.Va fflags . +On return, +.Va data +contains the number of times the timeout has expired since the last call to +.Fn kevent . +This filter automatically sets +.Dv EV_CLEAR +in +.Va flags +for periodic timers. +Timers created with +.Dv NOTE_ABSTIME +remain activated on the kqueue once the absolute time has passed unless +.Dv EV_CLEAR +or +.Dv EV_ONESHOT +are also specified. +.Dv CLOCK_REALTIME +is the reference clock for timers created with +.Dv NOTE_ABSTIME . +.Pp +The filter accepts the following flags in the +.Va fflags +argument: +.Bl -tag -width XXNOTE_TRACKERR +.It Dv NOTE_SECONDS +The timer value in +.Va data +is expressed in seconds. +.It Dv NOTE_MSECONDS +The timer value in +.Va data +is expressed in milliseconds. +.It Dv NOTE_USECONDS +The timer value in +.Va data +is expressed in microseconds. +.It Dv NOTE_NSECONDS +The timer value in +.Va data +is expressed in nanoseconds. +.It Dv NOTE_ABSTIME +The timer value is an absolute time; see discussion above. +.El +.Pp +Note that +.Dv NOTE_SECONDS , +.Dv NOTE_MSECONDS , +.Dv NOTE_USECONDS , +and +.Dv NOTE_NSECONDS +are mutually exclusive; behavior is undefined if more than one are specified. +If a timer value unit is not specified, the default is +.Dv NOTE_MSECONDS . +.It Dv EVFILT_FS +Establishes a file system monitor. +Currently it only monitors file system mount and unmount actions. +.It Dv EVFILT_USER +Establishes a user event identified by +.Va ident +which is not associated with any kernel mechanism but is triggered by +user level code. +The lower 24 bits of the +.Va fflags +may be used for user defined flags and manipulated using the following: +.Bl -tag -width "Dv NOTE_FFLAGSMASK" +.It Dv NOTE_FFNOP +Ignore the input +.Va fflags . +.It Dv NOTE_FFAND +Bitwise AND +.Va fflags . +.It Dv NOTE_FFOR +Bitwise OR +.Va fflags . +.It Dv NOTE_FFCOPY +Copy +.Va fflags . +.It Dv NOTE_FFCTRLMASK +Control mask for +.Va fflags . +.It Dv NOTE_FFLAGSMASK +User defined flag mask for +.Va fflags . +.El +.Pp +A user event is triggered for output with the following: +.Bl -tag -width "Dv NOTE_FFLAGSMASK" +.It Dv NOTE_TRIGGER +Cause the event to be triggered. +.El +.Pp +On return, +.Va fflags +contains the users defined flags in the lower 24 bits. +.El +.Sh CANCELLATION BEHAVIOUR +If +.Fa nevents +is non-zero, i.e., the function is potentially blocking, the call +is a cancellation point. +Otherwise, i.e., if +.Fa nevents +is zero, the call is not cancellable. +Cancellation can only occur before any changes are made to the kqueue, +or when the call was blocked and no changes to the queue were requested. +.Sh RETURN VALUES +The +.Fn kqueue +system call +creates a new kernel event queue and returns a file descriptor. +If there was an error creating the kernel event queue, a value of \-1 is +returned and +.Dv errno +is set. +.Pp +The +.Fn kevent +system call +returns the number of events placed in the +.Fa eventlist , +up to the value given by +.Fa nevents . +If an error occurs while processing an element of the +.Fa changelist +and there is enough room in the +.Fa eventlist , +then the event will be placed in the +.Fa eventlist +with +.Dv EV_ERROR +set in +.Va flags +and the system error in +.Va data . +Otherwise, +.Dv \-1 +will be returned, and +.Dv errno +will be set to indicate the error condition. +If the time limit expires, then +.Fn kevent +returns 0. +.Sh EXAMPLES +The following example program monitors a file

the +.Xr sigsetops 3 +interface is used to modify such data. +.Pp +When a signal +condition arises for a process, the signal is added to a set of +signals pending for the process. +If the signal is not currently +.Em blocked +by the process then it is delivered to the process. +Signals may be delivered any time a process enters the operating system +(e.g., during a system call, page fault or trap, or clock interrupt). +If multiple signals are ready to be delivered at the same time, +any signals that could be caused by traps are delivered first. +Additional signals may be processed at the same time, with each +appearing to interrupt the handlers for the previous signals +before their first instructions. +The set of pending signals is returned by the +.Xr sigpending 2 +function. +When a caught signal +is delivered, the current state of the process is saved, +a new signal mask is calculated (as described below), +and the signal handler is invoked. +The call to the handler is arranged so that if the signal handling +routine returns normally the process will resume execution in the +context from before the signal's delivery. +If the process wishes to resume in a different context, then it +must arrange to restore the previous context itself. +.Pp +.Em "struct sigaction" +includes the following members: +.Bd -literal -offset indent +void (*sa_sigaction)(int sig, siginfo_t *info, void *ctx);

+no action; stopping the process; or continuing the process. +See the signal list below for each signal's default action. +If +.Fa sa_handler +is set to +.Dv SIG_DFL , +the default action for the signal is to discard the signal, +and if a signal is pending, +the pending signal is discarded even if the signal is masked. +If +.Fa sa_handler +is set to +.Dv SIG_IGN , +current and pending instances +of the signal are ignored and discarded. +.Pp +Options may be specified by setting +.Em sa_flags . +.Bl -tag -width SA_NOKERNINFO +.It Dv SA_NODEFER +If set, then the signal that caused the handler to be executed is not added +to the list of block signals. +Please note that +.Fa sa_mask +takes precedence over +.Dv SA_NODEFER , +so that if the specified signal is blocked in +.Fa sa_mask , +then +.Dv SA_NODEFER +will have no effect. +.It Dv SA_NOCLDSTOP +If set when installing a catching function +for the +.Dv SIGCHLD +signal, +the +.Dv SIGCHLD +signal will be generated only when a child process exits, +not when a child process stops or continues. +.It Dv SA_NOCLDWAIT +If set, the system will not create a zombie when the child exits, +but the child process will be automatically waited for. +The same effect can be achieved by setting the signal handler for +.Dv SIGCHLD +to +.Dv SIG_IGN . +.It Dv SA_ONSTACK +If set, the system will deliver the signal to the process on a +.Em "signal stack" , +specified with +.Xr sigaltstack 2 . +If an alternate stack is not available, the default stack will be used. +.It Dv SA_RESETHAND +If set, the default action will be reinstated when the signal +is first posted. +.It Dv SA_RESTART +Normally, if a signal is caught during the system calls listed below, +the call may be forced to terminate +with the error +.Er EINTR , +the call may return with a data transfer shorter than requested, +or the call may be restarted. +Restarting of pending calls is requested +by setting the +.Dv SA_RESTART +bit in +.Ar sa_flags . +The affected system calls include +.Xr open 2 , +.Xr read 2 , +.Xr write 2 , +.Xr sendto 2 , +.Xr recvfrom 2 , +.Xr sendmsg 2 +and +.Xr recvmsg 2 +on a communications channel or a slow device (such as a terminal, +but not a regular file) +and during a +.Xr wait 2 +or +.Xr ioctl 2 . +However, calls that have already committed are not restarted, +but instead return a partial success (for example, a short read count). +.Pp +After a +.Xr fork 2 +or +.Xr vfork 2 +all signals, the signal mask, the signal stack, +and the restart/interrupt flags are inherited by the child. +.Pp +The +.Xr execve 2 +system call reinstates the default +action for all signals which were caught and +resets all signals to be caught on the user stack. +Ignored signals remain ignored;

status +is true, evaluates to the number of the signal +that caused the process to stop. +.El +.Sh NOTES +See +.Xr sigaction 2 +for a list of termination signals. +A status of 0 indicates normal termination. +.Pp +If a parent process terminates without +waiting for all of its child processes to terminate, +the remaining child processes are assigned the parent +process 1 ID (the init process

for the signal; +see +.Xr siginterrupt 3 . +.Sh RETURN VALUES +If +.Fn wait +returns due to a stopped +or terminated child process, the process ID of the child +is returned to the calling process. +Otherwise, a value of \-1 is returned and +.Va errno +is set to indicate the error. +.Pp +If +.Fn wait6 , +.Fn wait4 , +.Fn wait3 +or +.Fn waitpid +returns due to a stopped +or terminated child
