Probably for what I am doing 'run-shell-command' or `run-program' ('SHELL' or
EXECUTE) would be sufficient since I would be calling standard UNIX system
commands (such as ps or who or ping, etc). Is there any way to capture the unix
command output in a variable so it can be processed? It looks like the unix
command output is being printed to the screen and the value returned is 0.

Is there any documentation available that describes the differences between
'run-shell-command' and `run-program' and 'SHELL' and 'EXECUTE'?
