How to return integer in ruby main method

Question

Here is my code

if __FILE__ == $PROGRAM_NAME
  puts "tests"
  puts $PROGRAM_NAME
  return 1
end

I am trying to have a git pre-commit feature with ruby. And this pre-commit needs an integer return.

When I run this piece ruby code I got an error

`<main>': unexpected return (LocalJumpError)

As @minitech says, you want to use exit.

if __FILE__ == $PROGRAM_NAME
  puts "tests"
  puts $PROGRAM_NAME
  exit 1
end

Usually, 0 is success and 1 is failure in regards to exit codes. I don't know if Ruby changes them, though.
