don't understand PERL/'rename', only need one command

[nlz]

I want to change all the *.bmp files on my Ipod to be called cover.bmp . How do I do this? It should be recursive so it happens in all folders.

I really don't understand PERL...

rename doesn't work recursively so please use this command (thanks to ferret @ #perl )

 find . -name '*.bmp' -execdir mv {} cover.bmp \;
