Rename a group

groupmod -n new_group_name old_group_name

Replaces all instance of ‘<old string>’ with ‘<new sting>’ in all the files of the current directory.

perl -pi -e "s/<old string>/<new string>/g;" *

In this example, we will change all files with extension ‘.info’ to ‘.txt’.

Rename all *.info files in one folder

rename .info .txt *.info

That should read as..

rename <replace this string> <with this string> <in all these files>

Do the same operation recursively in a directory tree

find . -name "*.info" -exec rename .info .txt {} \;

Those double quotes around *.info are important - don’t remove them mm-kay?
