hi,

Thats right, the trap comand is used to ignore some signals.

One example could be:

# Ignore HUP, INT, QUIT now.

trap "" 1 2 3

This part of a /etc/.profile file.

Regards.

Re: ask for "trap" example

in a script file sometime you may not want the user to interupt your actions at a certain point....

trap '' int
or you can use
trap '' 2
or
stty '' \377

to restore the ctrl+c feature
stty intr '^C'
