+.Sh NAME
+.Nm glob
+.Nd shell-style pattern matching
+.Sh DESCRIPTION
+Globbing characters
+.Pq wildcards
+are special characters used to perform pattern matching of pathnames and
+command arguments in the
+.Xr csh 1 ,
+.Xr ksh 1 ,
+and
+.Xr sh 1
+shells as well as
+the C library functions
+.Xr fnmatch 3
+and
+.Xr glob 3 .
+A glob pattern is a word containing one or more unquoted
+.Ql \&?
+or
+.Ql *
+characters, or
+.Dq Li [..]
+sequences.
+.Pp
+Globs should not be confused with the more powerful
+regular expressions used by programs such as
+.Xr grep 1 .
+While there is some overlap in the special characters used in regular
+expressions and globs, their meaning is different.
+.Pp
+The pattern elements have the following meaning:
+.Bl -tag -width Ds
+.It Li \&?
+Matches any single character.
+.It Li \&*
+Matches any sequence of zero or more characters.
+.It Li [..]
+Matches any of the characters inside the brackets.
+Ranges of characters can be specified by separating two characters by a
+.Ql \-
+(e.g.\&
+.Dq Li [a0-9]
+matches the letter
+.Sq a
+or any digit).
+In order to represent itself, a
+.Ql \-
+must either be quoted or the first or last character in the character list.
+Similarly, a
+.Ql \&]
+must be quoted or the first character in the list if it is to represent itself
+instead of the end of the list.
+Also, a
+.Ql \&!
+appearing at the start of the list has special meaning (see below), so to
+represent itself it must be quoted or appear later in the list.
+.Pp
+Within a bracket expression, the name of a
+.Em character class
+enclosed in
+.Ql [:
+and
+.Ql :]
+stands for the list of all characters belonging to that class.
+Supported character classes:
+.Bl -column ".Li xdigit" ".Li xdigit" ".Li xdigit" -offset indent
+.It Li "alnum" Ta Li "cntrl" Ta Li "lower" Ta Li "space"
+.It Li "alpha" Ta Li "digit" Ta Li "print" Ta Li "upper"
+.It Li "blank" Ta Li "graph" Ta Li "punct" Ta Li "xdigit"
+.El
+.Pp
+These match characters using the macros specified in
+.Xr ctype 3 .
+A character class may not be used as an endpoint of a range.
+.It Li [!..]
+Like
+.Li [..] ,
+except it matches any character not inside the brackets.
+.It Li \e
+Matches the character following it verbatim.
+This is useful to quote the special characters
+.Ql \&? ,
+.Ql \&* ,
+.Ql \&[ ,
+and
+.Ql \e
+such that they lose their special meaning.
+For example, the pattern
+.Dq Li \e\e\e\&*\e[x]\e\&?
+matches the string
+.Dq \e\&*[x]\&? .
+.El
+.Pp
+Note that when matching a pathname, the path separator
+.Ql / ,
+is not matched by a
+.Ql \&? ,
+or
+.Ql * ,
+character or by a
+.Dq Li [..]
+sequence.
+Thus,
+.Pa /usr/*/*/X11
+would match
+.Pa /usr/X11R7/lib/X11
+and
+.Pa /usr/X11R7/include/X11
+while
+.Pa /usr/*/X11
+would not match either.
+Likewise,
+.Pa /usr/*/bin
+would match
+.Pa /usr/local/bin
+but not
+.Pa /usr/bin .

+.Xr glob 3 ,
+.Xr re_format 7
+.Sh HISTORY
+In early versions of
+.Ux ,
+the shell did not do pattern expansion itself.
+A dedicated program,
+.Pa /etc/glob ,
+was used to perform the expansion and pass the results to a command.
+In
+.At v7 ,
+with the introduction of the Bourne shell,
+this functionality was incorporated into the shell itself.
