Bash Trap Control+C
Do you want to catch control-c keyboard interrupts in your Bash program? Use the Bash builtin trap
command to catch system signals. The following runs control_c() when a
user interrupts the main() section with a Control-C (SIGINT)
#!/bin/bash
cleanup()
# example cleanup function
{
rm -f /tmp/tempfile
return $?
}
control_c()
# run if user hits control-c
{
echo -en "\n*** Ouch! Exiting ***\n"
cleanup
exit $?
}
# trap keyboard interrupt (control-c)
trap control_c SIGINT
# main() loop
while true; do read x; done
