how to prevent "ctrl-C" input
Hi
I have a script and its execution takes 40 - 60 minutes. The script is run on the console window of the machine. Script execution should not be broken by running ctrl-C under any circumstances. Is there a way to lock the window from any user input (ctrl-C in fact) till the end of the script execution. Thanks a lot. -A

One way: block SIGINT with a trap:
Code:
 trap 'echo "you typed ctrl/c"; ' INT
while true
do
 sleep 20
done

PS: if you run this code: you cannot stop it with ctrl/c, you will have to kill it from another process.

Another way.

man stty

For example to turn off interrupt and quit for that session:
stty intr ""
stty quit ""
