Are you using csh (or tcsh) for scripting? Again, DON'T.
For reasons why not, see:
<http://www.grymoire.com/Unix/CshTop10.txt>

<http://www.faqs.org/faqs/unix-faq/shell/csh-whynot/>
Use a Bourne-type shell for scripting (sh, bash, ksh, ash, zsh).

For information on writing shell scripts, you would do better in
the comp.unix.shell newsgroup.
