In csh, it's "foreach", like this (tested):
foreach luser (joe peter bill)
echo $luser
end
The csh man page says: "Both foreach and end must appear alone on
separate lines."
But you should not use csh for scripting[1]. Instead, stick to standard
sh (tested):
for luser in joe bill ted; do echo $luser; done
But that's ugly. Unless there's a good reason to stick with shell
scripts, consider using Perl or Python[2] from the start.
[1] Google for it.
[2] I'd lean towards Python currently. Shame about the string
interpolation, though.
