Error messages for the unknown - bash

[whatthefunk]

My bash scripts contain error messages for errors which I think might occur, but sometimes something happens that I did not expect. I would like to have a generic error message for these times. How do I write this into my scripts?

Hm, an idea is to send all stderr to /dev/null and in every command to check the return code. If it's an error code, run a function which contains your generic error message.
It might be a better way.

In general it's a *) in the case statement. If you are using ifs then it's the last else case.
