Could you show me some trap examples?

the trap command is used within the script to ignore signal or not?

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.

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'
