Any chance you can re-post using the forum formatting to get a better idea of the formatting?

How are you defining $USER?

Yea sure!

My understanding was that if you use $USER, OS X will plug in the current logged in user.

So when you run it as you, locally, it knows that you are $USER. But I believe if you're trying to automate this you'll need to define $USER.

Something like:

USER=`ls -l /dev/console | cut -d " " -f 4`

That worked, thanks so much!

Sure thing!

EDIT: I'll leave my post below just in case, but it looks like you're all set!

As @emilykausalik hinted at, the $USER variable may not be getting defined correctly. A general rule to follow when scripting for Casper deployed scripts is to define any user names in your script by getting the logged in user, or cycling over user directories, etc. I would not rely on built in bash variable stuff because the scripts are being run under a root context by default, so it changes the whole interaction. Its not the same as running a script from the Terminal directly.

You can get the logged in user (assuming someone is usually logged in) by doing something like

USER=$(ls -l /dev/console | awk '{print $3}')

There are about 4-5 other ways to do this though, including using stat, python code and a few others. Use whatever works, but get the username within the script and then plug that variable into the rm lines and see what happens.
Also make sure 'rm' is lower case. I can't tell if the upper case of those in your post was just because of auto correct or if that's actually how they were written. 'RM' will not work at all.

might want to spell RM as rm, although on a case insensitive OS I suppose that might work. assuming all the # are missing because they made the text bold in the post, when posting scripts use the >_ button it gives you a pretty good hint that its the right thing by giving you a

#!/bin/sh

to know that its a script section...
after you get your $USER variable sorted your may need to consider why you have two asterisks on the second rm command I probably would just remove both of them.
