An illustrative example on how to use ZSH traps.

nap.sh

#!/bin/zsh

nap() {
	print "Taking a nap..."
	command sleep 3
}

TRAPINT() {
	# Remove the printed '^C' from the console.
	print -n "\x1b[2D"
	# Initiate anarchy."
	print "You're not the boss of me, CTRL-C!"
	command sleep 0.2
	# Restart our interrupted nap-nap...
	nap
	return 0
}

nap
print "All done..."
