File::FnMatch - simple filename and pathname matching
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;
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.
Returns true if PATTERN matches STRING, undef otherwise. FLAGS may be the bitwise OR'ing of any supported FNM_* constants (see below).
Do not treat a backslash ('\') in PATTERN specially. Otherwise, a backslash escapes the following character.
Prohibit wildcards from matching a slash ('/').
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.
qr//i
None by default. The export tag :fnmatch exports the fnmatch function and all available FNM_* constants.
:fnmatch
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:]]).
[abcdef]
[a-f0-9]
[a-f0-9XYZ]
[[:xdigit:]]
[![:space:]]
Locale influences the meaning of fnmatch() patterns.
Most UNIX-like systems provide an fnmatch implementation. This module will not work on platforms lacking an implementation, most notably Win32.
