printf format codes are also used by scanf, and String::Scanf provides format_to_re()

So, maybe something like:

# Untested
# Use a printf/scanf pattern to match file names

use String::Scanf qw();
use File::Find::Rule;

my @w = qw( . ); # where to look

my $f = $ARGV[0];
$f =~ s/[\012\015]+$//; # universal chomp()

my $r = String::Scanf::format_to_re($f);

my @files = File::Find::Rule->file()
                            ->name( $r )
                            ->in( @w );
