File renaming script/freeware/something

Not sure whether this is the best place to ask for freeware, but help us out any instead of being pedantic faggots

SO. I have a shitload of files whose only filenames consist of four digits, ie. '0054'. I have lots of DIFFERENT files that commonly have the same filename, 0054, but in different directories.

I want an auto filename changer so I can store everything in one directory. Does that make sense?

Any help much appreciated

man rename

or in one line :

find . -name "*0054*" | xargs -n1 -i{} mv {} /FINALDIR/`md5sum {}`

something like that.

( caca )

man rename

Total Commander.
Branch view (Ctrl+B) + Mass-Renamer (Ctrl+M) solve this problem.
