Since you've gotten an answer to the question you asked, let me only note that 
both sh and csh support the -x flag, which causes the shell to echo the 
commands as it runs.  This is extremely helpful for debugging.


Where is the this -x flag coded at? Do the executed lines roll fast off the screen or can I slowly step through the script a line at a time?

Thanks for this bit of information.
