Greetings,

I have produced a lengthy bourne shell script to perform a sequence
of system administration tasks for SCO UNIX users. We are looking for a 
method that we can use to put this shell script on customer sites that
require it but protect it at the same time from being hacked around.

Whether that be a "shell compiler" or some other mechanism I am open
to advice. We need to protect our time and investment in this little project 
and stop it from being copied and stolen.    

If anyone has any ideas please help.

I do not like to ask for anything without giving something in return
so I include a one-liner that I have found useful.
It detects control characters that have mistakenly been placed in
filenames and displays the control character in the form \nnn.
Using this, administrators can inform users in advance why they cannot
retrieve mistyped files.

find / -type f -print | xargs -t ls -qb 2>/dev/null | grep '\\'
