I also thought this (Colin's comment), was the problem so I changed
some of my bash scripts to test it. At least on my slink box, that
isn't the answer.
All of these worked : #!/bin/sh, # !/bin/sh, #! /bin/sh and
the script even worked _without_ any #! line _at all_!!! I have no
idea why it worked, but it does?????
slink, 2.2.13.

For any problem there is a solution that is simple, quick, and
ultimately worse than the problem.
