typo checking Les is on the case!

Yes that should be $users in all locations.
And yes the rm line is dangerous as it will try and run whether the cd
happens or not. "-1" makes things be a single column from the ls
command.

A better form would be :

for user in `ls -1 /home`
do
 for dotfile in .gnome .mozilla .cxoffice
 do
  rm -rf /home/$user/$dotfile
 done
done

If you know you want to clobber all the same files in all /home
directories

rm -rf /home/*/.mozilla

will remove the .mozilla directory in every /home directory on the
system.

As said in Spiderman "With great power come great responsibility.".
rm -rf is tremendously powerful. Use a ls -lr first to test what you are
about to remove!
