Shell Script to List Directories...

Hello,

I am new to shell scripting. I am running Red Hat using Bash. I am trying to create a little script that will loop through the -sub-directories of the systems home directory, and then recursively zip up the contents of each one saving it as the name of that particularly directory.

I cannot figure out how to do this. Can anyone help?

Thanks

#!/usr/bin/local/bash
#
# cd to the directory you want to backup first.
# You could also easily modify the script to take
#command line arguments.
for user in $( ls . )
do
tar czvf /back_up_dir/$user.tar.gz $user
done
