Well, _both_ scripts won't work on SUNs;
I tested SUN OS 3.3, 3.5 and 4.0.3.

Obviously some sed's don't like commands being seperated the
way you do it, and there seem to be different ways for
various csh's to interpret lots of backslashes at the end of a line.


The following script uses ';' to seperate
sed-commands and will work on HP-UX as well as Ultrix and SUN-OS:


#!/bin/csh -f
# Command to print stdin with a Subject: line
set title=`tee temporary | sed -e '/^Subject: /\\!d;s/Subject: //'`
echo $title
