how to kill script with trap command

cybermilky — Mon, 14 Oct 2002 03:34:54 GMT

Does anyone know how to create a shell script that has endless loop of printing the word "looping" on the screen continuously and cannot be interrupted by Ctrl-C break key. How do I kill the script then?
How do I write this shell script by using 'trap'?

I think you only need to specify this code at the beginning of your script.
trap '' 2

2 is meant for interupt or ctrl + c.

Hi,

My guess is that you would be able to kill the script by suspending it (CTRL+Z). Then, find out the job id with the "jobs" command and kill the job using "kill" (e.g. "kill %1" if the job number is 1).

Regards,

Vincent

Hi

Please do not use the expertise on the forum to answer your exam or project problems.

We will help if you at least made an attempt and posted your attempt at a script.

But we will not do your project/homework for you.
