grab shell script error
How do I capture an error for any command I use.

For e.g if i try to zip a file and the file is not there. The regualr $? -gt 0 only tells its un-successful but won't tell me that the file is not there when I run through a script. How can I capture this error?

for e.g.. zip $x.zip $x
file is not there

I need grab the return code as well as error in the script. How can I do that?
