Shell Programming and Scripting

Just learning how to script and am trying to create a script that will:

*change ownership to nobody
*change permissions to rw
*tar the directory
*back it up to a share
*remove backups older than 14 days

I will be doing this on a RHEL 5.3 box on my home network as practice for work that I will be doing in the fall. I do have a scripting book to also help me learn syntax and meanings of commands.

Thanks for help with any or all of the above items.

Check the man for each of the following commands:
chown will surely help you. Check for -R option too
chmod in that case, -R for recursivity as well.
The command tar there. Options you might need include -z for zip, -c and -f.
cp (copy), mv (move) or rsync (remote copy).
Check for the find command, options -mtime or -ctime, alonside with rm command.

Thanks so much for your time. I am sure these tips will be very helpful.
