Simple utility to recursively search one or more specified directories for duplicate files. Usage: finddups.pl dir1 [dir2 ... [dirN] ...] Written originally in 1998 when I was learning Perl, and tweaked over the years as I learned more. It's 1234 bytes long now, and doesn't seem to need any more tweaking, so I haven't touched it in a long time.
