Note for Joeyg's example: shells will try to glob (find matching files names for) the ** characters.

In bash (as an example) you can turn off globbing with
Code:
set -o noglob

NAME
Text::Glob - match globbing patterns against text SYNOPSIS
use Text::Glob qw( match_glob glob_to_regex ); print "matched " if match_glob( "foo.*", "foo.bar" ); # prints foo.bar and foo.baz my $regex = glob_to_regex( "foo.*" ); for ( qw( foo.bar foo.baz foo bar ) ) { print "matched: $_ " if /$regex/; } DESCRIPTION
Text::Glob implements glob(3) style matching that can be used to match against text, rather than fetching names from a filesystem. If you want to do full file globbing use the File::Glob module instead. Routines match_glob( $glob, @things_to_test ) Returns the list of things which match the glob from the source list. glob_to_regex( $glob ) Returns a compiled regex which is the equivalent of the globbing pattern. glob_to_regex_string( $glob ) Returns a regex string which is the equivalent of the globbing pattern. SYNTAX
The following metacharacters and rules are respected. "*" - match zero or more characters "a*" matches "a", "aa", "aaaa" and many many more. "?" - match exactly one character "a?" matches "aa", but not "a", or "aaa" Character sets/ranges "example.[ch]" matches "example.c" and "example.h" "demo.[a-c]" matches "demo.a", "demo.b", and "demo.c" alternation "example.{foo,bar,baz}" matches "example.foo", "example.bar", and "example.baz" leading . must be explictly matched "*.foo" does not match ".bar.foo". For this you must either specify the leading . in the glob pattern (".*.foo"), or set $Text::Glob::strict_leading_dot to a false value while compiling the regex. "*" and "?" do not match / "*.foo" does not match "bar/baz.foo". For this you must either explicitly match the / in the glob ("*/*.foo"), or set $Text::Glob::strict_wildcard_slash to a false value with compiling the regex. BUGS
The code uses qr// to produce compiled regexes, therefore this module requires perl version 5.005_03 or newer. AUTHOR
