Command to rename multiple file in one go

This command can be used to rename all the files with extension .xls( in this case) to .ods files. It can be used for other files with certain extension.


There are 4 alternatives - vote for the best!

Terminal - Alternatives
rename 's/.xls/.ods/g' *.xls
for f in ./*.xls; do mv "$f" "${f%.*}.ods"; done

An entirely shell-based solution (should work on any bourne-style shell), more portable on relying on the rename command, the exact nature of which varies from distro to distro.
