To all: thanks for your input!


Today I learned: $PATH is not the same for myself and root.


@Don--I typed Cleanup in the post but I wasn't doing so in the script.
Here is the output of those commands:
Code:

@ RudiC and @bakunin


Thanks to your guidance, I strongly suspect the problem is not having my home directory is root's $PATH.

Cleanup3 was only running because I had placed a copy of it in /usr/local/bin.


Now I just need to figure out how to write bakunin's script!
