rename several files in bash or python
 

Hi,

i would like to build a bash script or a python program that list a directory structure and, for all the files that it find, removes the extension java,v to java. How i do that?

Regards,
Pedro

I think i found it.

for file in *.txt; do mv $file `echo $file | sed 's/\(.*\.\)txt/\1TXT/'`; done

But, i've another question.

If i want to run this script inside each directory, how should i do it?

thanks
