One of my first memories with Perl is reading about find2perl. I had no idea that you could translate shell to perl so easily. Anyway, using find2perl is very easy and demonstrates how to use File::Find.

[michael]$ find2perl /path/to/directory -name '*.b' -exec rm {} \;

(mostly copied and pasted into the shell) which prints a complete File::Find based Perl script ready to run. It's a little verbose, so I've removed some of the less important lines for the sake of clarity.

#! /usr/bin/perl -w

use strict;
use File::Find ();

sub wanted {
    /^.*\.b\z/s &&
    (unlink($_) || warn "$name: $!\n");
}

# Traverse desired filesystems
File::Find::find({wanted => \&wanted}, '/path/to/directory');
exit;
