 for i in *\ *; { mv "$i" $(echo $i | sed 's/ /_/g'); }   

This one goes through an entre directory changing all <SPACES> in each filename into underscores "_". Great for mp3s downloaded from goofy windows users.
 
ie. Madonna - Ray of Light.mp3
 
becomes:   Madonna_-_Ray_of_Light.mp3
 
It makes dealing with files from the command-line much easier.

that was taken from www.darkbytes.net/html/oneliners.html ... some very cool stuff on www.darkbytes.net including a text book of a book called underground, not done yet but its been great so far :)
