GLOB(7) 		       BSD Miscellaneous Information Manual			  GLOB(7)

NAME
     glob -- shell-style pattern matching

DESCRIPTION
     Globbing characters (wildcards) are special characters used to perform pattern matching of
     pathnames and command arguments in the csh(1), ksh(1), and sh(1) shells as well as the C
     library functions fnmatch(3) and glob(3).	A glob pattern is a word containing one or more
     unquoted '?' or '*' characters, or ``[..]'' sequences.

     Globs should not be confused with the more powerful regular expressions used by programs
     such as grep(1).  While there is some overlap in the special characters used in regular
     expressions and globs, their meaning is different.

     The pattern elements have the following meaning:

     ?	     Matches any single character.

     *	     Matches any sequence of zero or more characters.

     [..]    Matches any of the characters inside the brackets.  Ranges of characters can be
	     specified by separating two characters by a '-' (e.g. ``[a0-9]'' matches the letter
	     'a' or any digit).  In order to represent itself, a '-' must either be quoted or the
	     first or last character in the character list.  Similarly, a ']' 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 '!' 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.

	     Within a bracket expression, the name of a character class enclosed in '[:' and ':]'
	     stands for the list of all characters belonging to that class.  Supported character
	     classes:

		   alnum     cntrl     lower	 space
		   alpha     digit     print	 upper
		   blank     graph     punct	 xdigit

	     These match characters using the macros specified in ctype(3).  A character class
	     may not be used as an endpoint of a range.

     [!..]   Like [..], except it matches any character not inside the brackets.

     \	     Matches the character following it verbatim.  This is useful to quote the special
	     characters '?', '*', '[', and '\' such that they lose their special meaning.  For
	     example, the pattern ``\\\*\[x]\?'' matches the string ``\*[x]?''.

     Note that when matching a pathname, the path separator '/', is not matched by a '?', or '*',
     character or by a ``[..]'' sequence.  Thus, /usr/*/*/X11 would match /usr/X11R6/lib/X11 and
     /usr/X11R6/include/X11 while /usr/*/X11 would not match either.  Likewise, /usr/*/bin would
     match /usr/local/bin but not /usr/bin.

HISTORY
     In early versions of UNIX, the shell did not do pattern expansion itself.	A dedicated pro-
     gram, /etc/glob, was used to perform the expansion and pass the results to a command.  In
     Version 7 AT&T UNIX, with the introduction of the Bourne shell, this functionality was
     incorporated into the shell itself.
