Hi, I'm new in Ruby and i found a little problem, make a simple program
with a infinite loop to print one String. I use linux (Kubuntu) and when

Check on your terminal if there is any key binding for CRTL+C like "Copy
to Clipboard".

# cat loop.rb
while true do
puts "test"
sleep 1
end
# ruby loop.rb
test
test
loop.rb:3:in `sleep': Interrupt
        from loop.rb:3

One single CTRL+C works fine for me here. I'm using the XFCE terminal.

hi,

instead of working with an infinite loop, you could trap the Crtl-C
signal to make your loop come to an end.

stop = false
trap('INT') { stop = true }

until stop
      # do your string stuff
end
