renaming multiple files

[Priemsy]

hi everyone,

just wondering how to rename multiple files. I've got a large mp3 collection which all need .mp3 added to their filename. I used to know how to do it but I've forgotten.

Thanks for your help

Something like

for i in *
do
mv $i ${i}.mp3
done

would chuck a .mp3 extension indiscriminately on everything in the current directory.
A further refinement might be to substitute the following for the *

`ls |grep -v \.mp3$`

mmv '*' '#1'.mp3
