+.sh NAME
+ps \*- process status
+.sh SYNOPSIS
+.bd ps
+[
+.bd alx
+]
+.sh DESCRIPTION
+.it Ps
+prints certain indicia about active
+processes.
+The
+.bd a
+flag asks for information about all processes with teletypes (ordinarily
+only one's own processes are displayed);
+.bd x
+asks even about processes with no typewriter;
+.bd l
+asks for a long listing.
+Ordinarily only the typewriter number (if not one's own)
+and the process number are given.
+.s3
+The long listing is columnar and contains
+.s3
+.lp +5 0
+A number encoding the state (last digit)
+and flags (first 1 or 2 digits) of the process.
+.s3
+The priority of the
+process; high numbers mean low priority.
+.s3
+A number related in some unknown way to the
+scheduling heuristic.
+.s3
+The last character of
+the control typewriter of the process.
+.s3
+The process unique number
+(as in certain cults it is possible
+to kill a process if you know its true name).
+.s3
+The size in blocks of the core image of the process.
+.s3
+The last column if non-blank tells the core
+address in the system of the
+event which the process is waiting for;
+if blank, the process is running.
+.s3
+.i0
+.dt
+Unfortunately if you have forgotten the number of a process
+you will have to guess which one it is.
+Plain
+.it ps
+will tell you only a list of numbers.

+.sh BUGS
+The ability to see, even if dimly,
+the name by which the process was invoked would
+be welcome.
