Dear All,

Can I prevent the user from terminating the program by pressing "Ctrl+C" after running the script developed by me?

Please advise.
I am using Sun Solaris 8 & ksh.

Thanks.

trap 'echo "Ctrl-C disabled" ' 0 1 2 3

trap 'echo "Ctrl-C disabled" ' 0 1 2 3

is more accurately written

trap 'echo "SIGINT is trapped, which may or may not be Ctrl-C"' 2
