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.
- 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).
- 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.
None by default. The export tag :fnmatch exports the fnmatch function and
all available FNM_* constants.
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.
Most UNIX-like systems provide an fnmatch implementation. This module will
not work on platforms lacking an implementation, most notably Win32.
