[plug] ridiculous UNIX one-liner

Damnn funny. I wrote that on Cygwin to match dupes in my housemates' MP3 
collection. Mine is all off my CDs, so I don't need to :-) (6gigs of ogg 
files ripped off just-cleaned CDs using CDDA transfers on a good quality 
drive... why do people /want/ to listen to stuff they've downloaded when 
its a dodgy 128kbps MP3?).

*smacks head*
Also the the space delimeted cuts can be replaced with byte-range cuts 
since the MD5sum part is constant-length. Realised that later.

This made it apparent to me how badly I need to learn awk and sed - 
since currently I find myself using inline perl do do the jobs awk and 
sed are usually used for.

Anybody know of a good tute on awk/sed?
