sed/csh interaction

[Paul Gerwitz]

Here is an interesting phenomena for you u**x hackers.  Below are two
variations of the same script which takes a news article and strips out the
subject line for use later.  The second variation was created because the
csh on a different machine would not take the origonal script.  The
question is "why won't this one script work on both machines.

File 1 
Origonal script
works on Decstation 3100 @ Ultrix 3.0
DOES NOT WORK on HP835 at HP-UX 7.0

#!/bin/csh -f
# Command to print stdin with a Subject: line
set title=`tee temporary | sed -e '/^Subject: /\\!d\\\
 s/Subject: //'`
 echo $title
-------------------------------------------------------
File 2
Modified origonal
Works on HP-UX
DOES NOT WORK on Ultrix

#!/bin/csh -f
set title="`tee temporary | sed -e '/^Subject: /\\!d \\
 s/Subject: //'`"
echo $title

The script is run as such:  file1 < testdata

Here is the test data file:
