Exception-handling in Shell programs

Hi all,

I am writing a set of scripts and some of these are nested within others. I want to be able to execute a single high-level script at the command-line, which in turn may invoke other scripts as required, and when a failure occurs in any of the nested scripts, I want to be able to track the deepest-nested command causing the failure and preferably a call trace.

To do this, trap could be used I was told but I am not sure trap's functionality is enough for my need. What do you think is the best way here?

It's a constraint at this place that I use only shell and not a full-blown programming language. Any help from you guys is greatly appreciated.

Best Regards,
Chaitanya
