Hello,

I have about 2k of file that are currently in lower case like:

file_one.cfr
file_two.cfr
....

I am searching for a fast way to rename them to upper case so they would be like;

FILE_ONE.cfr
FILE_TWO.cfr
....

If I use from my shell;

for i in *; do mv $i `echo $i | tr [:lower:] [:upper:]`; done

I can get all file and the file extensions to upper case.

But the extension should remain in lowercase, so my approach does not work.

Any programming language is welcome.
