Over-riding TRAP in Child
Hi,

I'm using Ksh on HP 10.2.

My parent shell script has ignored INT signal using trap command.

trap "" 2 3 .... (other signals)

This script calls another script in which INT signal should be active and should not be ignored.

I browsed the net and found out that in ksh, once a particular signal is ignored, then subsequent trap command executed in child shells will have no effect on the disposition of signal.

Can anyone tell me how do I initialize INT signal, in my child shell, to exit from child shell, even though INT should still be ignored in my parent shell ?

Thanks in Advance....

trap "exit 0" INT

And you should use the symbolic signal names rather than the numbers for maximum portability.
