Hi, I'm trying to write an exit routine for ksh script which ideally should capture the user input "control c" and then exit the script gracefully. Any ideas and suggestions ? Thanks,

Control C should cancel out of the script itself.

If a script is at a certain critical stage where a user cancel might leave things in a bad state, the script will want to disable the user cancel request for this portion of the script. Also, I have some scripts that make use of temporary files. If the user cancels, I do honor the cancel request, but I intercept it so that I can do some house cleaning first. You can define what you want to happen when a certain signal is detected via the trap command. The trap command watches for a certain signal, not a certain key. Signal 2 is interrupt signal, usually mapped to Ctrl-C. If the trap code does not exit, the script will continue its execution after the trap executes. Run the following script and try to cancel it: #!/bin/ksh trap 'echo Ouch' 2 sleep 3 sleep 3 sleep 3 sleep 3 sleep 3 sleep 3 exit 0 Following is a signal 2 trap that does some stuff and then exits. Just for testing, it exits with status code 3, but could be zero or whatever: trap 'echo "You pressed interrupt key";\ echo "doing some cleanup";\ exit 3' 2
