In Ruby I have the following:
# Trap Interrupts
trap("INT") do
puts "Shutting down..."
exit
end
When I interrupt the program, the following is printed (Mac OSX Lion):
^CShutting down…
Is there any way to hide ^C from within Ruby?
Whether control characters are echoed is a property of the tty you’re using.
stty -echoctlis the Unix way to disable echoing of control characters. You can run this command from within your Ruby script and achieve the same effect if you’re using a Unix-ish system.
