FnMatch(3) User Contributed Perl Documentation FnMatch(3) 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. SEE ALSO File::Glob, POSIX::setlocale, fnmatch(3) AUTHOR Michael J.
