csh to bash syntax conversion

[AshleySummy]

I'm an early beginner in scripting, but I've been asked to do some for a job. I've been given some scripts to work with in csh but I need to make them bash-friendly. I'm getting these "bad substitution" errors for the following syntax:

${?TARGET_CPU}

I've figured out what the syntax means in csh, but I'm having a really hard time finding the equivalent in bash. Any insight or suggestions would be greatly appreciated

Thanks,
Ashley

Time to invest in some bash-for-beginners books. There are a number available, and quite a bit of online documentation as well. Remember, google is your friend! You have way too much to learn to ask all of your questions here. Once you have a handle on your basic problems, then come back here with questions you haven't been able to resolve yourself first.

Oh gee, what's Google? You know, somehow I managed to stumble my way into a Linux forum to ask my questions but didn't know to Google them first. I'm not an idiot, yes I know how to google things and look up bash tutorials, but the specific conversion I was looking for was quite difficult to find. Sorry to bother you with my problems. I asked for help or suggestions, not your condescending bs. In the future, spare me.

What does it mean in csh?

Like most people who write scripts, I don't use csh, but if you tell us what it does, we may be able to help.
