FW: Cannot find process

[Roger Oberholtzer]

Does the script start another program? If the script starts a program in
the background, the script could finish and exit, leaving the other
program running, not the script.

When you run the script, do you get a prompt again? Or does the program
keep running so you cannot type more commands?

If a program is running in the foreground, you can type ctrl-Z. This
puts it in the background.  A simple 'ps' will then show the program.

What is the very first line in the script? It is something like

	#!some_program

If so, the first item after the #! ('some_program' in my example) is the
program that will run the script, and the one you should look for in
process lists. The script file you ran or even a shell will not be what
you will see. It will be 'some_program'.
