Some time ago I wrote some shell scripts to run in /bin/sh, and for some
reason, they ran in /bin/csh.

The fix is to insert a line at the beginning of the script:

#!/bin/sh

This, for some [magic] reason, forces the script file to run under
the Bourne shell.  Maybe some guru/wizard/hacker out ther can
elaborate on why this happens.  All I know (and care about) is that
it works! ;)

Also, another thing that works is to insert 1 space before your
first word in the script:

 echo "Super Script: POWERBACK"
echo " "
echo "Another marvelous script written by ME"
..
..
.. all the things that the script does
..
..
exit 0

Give them a try!  If they don't work, well, it's due to some unique
feature/bug about Ultrix that I'm not familiar with!
