how to prevent a user from cancelling a script

[pujas]

Hi,

I wanted to know the way of preventing anyone including myself to do a ctrl-c on the script running.

Basically even if i do a ctrl-c the script should not stop running.

Thanks

i'sm relatively new to unix so could you tell me what "" and 1 2 3 15 means.

Where does ctrlc and my unix shell pgm name come in this cmd.

thanks

In your shell man page, pay attention to the trap builtin.

The "" 1 2 3 15 are trap signals that unix interperets. Without looking in a book to tell you what each signal means. Basically it has to do with not allowing CTRL+C CTRL+~ etc... To disable them use the command trap 1 2 3 15 with out the "". I tend to use these commands in .profiles as well to stop uses breaking out to a shell prompt.
