NAME

       File::FnMatch - simple filename and pathname matching

SYNOPSIS

	 use File::FnMatch qw(:fnmatch);    # import everything

	 # shell-style: match "/a/bc", but not "/a/.bc" nor "/a/b/c"
	 fnmatch("/a/*", $fn, FNM_PATHNAME|FNM_PERIOD);

	 # find our A- executables only
	 grep { fnmatch("A-*.exe", $_) } readdir SOMEDIR;

DESCRIPTION

       File::FnMatch::fnmatch() provides simple, shell-like pattern matching.

       Though considerably less powerful than regular expressions, shell patterns are nonetheless useful and familiar to a large audience of end-
       users.

   Functions
       fnmatch ( PATTERN, STRING [, FLAGS] )
	   Returns true if PATTERN matches STRING, undef otherwise.  FLAGS may be the bitwise OR'ing of any supported FNM_* constants (see below).

   Constants
       FNM_NOESCAPE
	   Do not treat a backslash ('') in PATTERN specially.  Otherwise, a backslash escapes the following character.

       FNM_PATHNAME
	   Prohibit wildcards from matching a slash ('/').

       FNM_PERIOD
	   Prohibit wildcards from matching a period ('.') at the start of a string and, if FNM_PATHNAME is also given, immediately after a slash.

       Other possibilities include at least FNM_CASEFOLD (compare "qr//i"), FNM_LEADING_DIR to restrict matching to everything before the first
       '/', FNM_FILE_NAME as a synonym for FNM_PATHNAME, and the rather more exotic FNM_EXTMATCH.  Consult your system documentation for details.

   EXPORT
       None by default.  The export tag ":fnmatch" exports the fnmatch function and all available FNM_* constants.

PATTERN SYNTAX

       Wildcards are the question mark ('?') to match any single character and the asterisk ('*') to match zero or more characters.  FNM_PATHNAME
       and FNM_PERIOD restrict the scope of the wildcards, notably supporting the UNIX convention of concealing "dotfiles":

       Bracket expressions, enclosed by '[' and ']', match any of a set of characters specified explicitly ("[abcdef]"), as a range ("[a-f0-9]"),
       or as the combination these ("[a-f0-9XYZ]").  Additionally, many implementations support named character classes such as "[[:xdigit:]]".
       Character sets may be negated with an initial '!' ("[![:space:]]").

       Locale influences the meaning of fnmatch() patterns.

CAVEATS

       Most UNIX-like systems provide an fnmatch implementation.  This module will not work on platforms lacking an implementation, most notably
       Win32.

NAME

       fnmatch - match filename or pathname

SYNOPSIS

       #include <fnmatch.h>

       int fnmatch(const char *pattern, const char *string, int flags);

DESCRIPTION

       The fnmatch() function checks whether the string argument matches the pattern argument, which is a shell wildcard pattern.

       The flags argument modifies the behavior; it is the bitwise OR of zero or more of the following flags:

       FNM_NOESCAPE
	      If this flag is set, treat backslash as an ordinary character, instead of an escape character.

       FNM_PATHNAME
	      If  this	flag  is  set,	match  a  slash  in  string only with a slash in pattern and not by an asterisk (*) or a question mark (?)
	      metacharacter, nor by a bracket expression ([]) containing a slash.

       FNM_PERIOD
	      If this flag is set, a leading period in string has to be matched exactly by a period in pattern.  A  period  is	considered  to	be
	      leading if it is the first character in string, or if both FNM_PATHNAME is set and the period immediately follows a slash.

       FNM_FILE_NAME
	      This is a GNU synonym for FNM_PATHNAME.

       FNM_LEADING_DIR
	      If  this	flag (a GNU extension) is set, the pattern is considered to be matched if it matches an initial segment of string which is
	      followed by a slash.  This flag is mainly for the internal use of glibc and is implemented only in certain cases.

       FNM_CASEFOLD
	      If this flag (a GNU extension) is set, the pattern is matched case-insensitively.

RETURN VALUE

       Zero if string matches pattern, FNM_NOMATCH if there is no match or another nonzero value if there is an error.

CONFORMING TO

       POSIX.2.  The FNM_FILE_NAME, FNM_LEADING_DIR, and FNM_CASEFOLD flags are GNU extensions.
