Thank you kindly for your help. I'll make the changes to my syntax that you describe. However, to answer some of your concerns:

I have that in there for now, because I originally had several scripts being called, instead of knowing how to get them all as functions in one script, and I wanted to make sure I had an easy way to change all of their paths if I needed to.

[QUOTE=cfajohnson;302401579][indent]

Code:
export DEEP

Why are you exporting DEEP? Are you calling another script that will need it?
Because until I exported it, this function flatly refused to believe its existence - hence the subject of the post. It would always return a blank.

The only line of importance, really, was the "echo $DEEP", since, if $DEEP had no value (which was the problem I was experiencing), then the rest of the stuff would fail, but if $DEEP had a value, it worked.

Once I made the change that I posted (export DEEP=blahblahblah), it worked magic.

If you really want to view a bunch of cringe-worthy code, I'll be happy to PM you the whole sad script, but, the reality is, I'm just trying to slam a hodge-podge of what little I know about bash scripting into a workable tool that will take the useless output from the configuration reports of a SYMC firewall and convert it into Cisco commands. I'm a network guy - once it gets past layer four, I stop caring. Smilie
