I have a script in which I set off sigalrm (14) in a background subscript that kills itself.
Currently I trap for sigalrm prior to entering a forever loop which calls a function to set off the alarm again.
I think I should be resetting the trap command within the loop but am not sure from the documentation.
Should I place a trap <go-to-function> SIGALRM within the loop or should I just reset it in the loop with trap 14?
It is not clear from the man page if reset would use <go-to-function> as the default. If not what is the default destination of the ALRM trap when reset without a user specified destination? Just trying to clarify this trap command, thanks.

I think you're going to have to create a mock-up script which follows the execution/function-call-order and place some debug echos in there to figure out exactly what it is doing.

I appreciate the idea of mocking up but feel that I need a tutorial or definitions related to trap-ing.
Please reread the last 4 sentences of #1. Those are the questions I have and feel should be stipulated regarding the trap command.

In addition to what you see in the SHELL BUILTIN COMMANDS in "man bash", did you read this chapter of the ABS? Did you read this part of the POSIX specification?

Didier, U R always with it, TNX. Yes I had scanned the ABS but was stealing their info on progress bars at the time so am going back cuz I saw some other goodies on that page too.
Wasn't aware of the POSIX specs but am going to have a set down to examine that as well.
THANKS again.
