Perl has a wonderful built-in function to expand wildcards:
glob. The trick is to use the {} patterns. They don't require files to exist.
So we just translate your patterns to the {} versions. The range operator (..) helps us a lot, as does evaluated regexes (/e flag).
#!/usr/bin/perl
use strict;
use warnings;
my @list = <DATA>;
chomp @list;
for my $pattern (@list) {
# Handle the . wildcard
$pattern =~ s/\./{0,1,2,3,4,5,6,7,8,9}/g;
# Handle the ranges
$pattern =~ s/\[([^\]]+?)\]/'{' . expand_brackets($1) . '}'/eg;
# Uncomment this to see how the patterns look before being passed
+to glob
# print $pattern, "\n";
print "$_\n" for glob($pattern);
}
sub expand_brackets {
my $pattern = shift;
$pattern =~ s/\b(\d+)\-(\d+)\b/join ',', $1 .. $2/ge;
return $pattern;
}
