$ ri Kernel#exit
------------------------------------------------------------ Kernel#exit
      exit(integer=0)
      Kernel::exit(integer=0)
      Process::exit(integer=0)
------------------------------------------------------------------------
      Initiates the termination of the Ruby script by raising the
      SystemExit exception. This exception may be caught. The optional
      parameter is used to return a status code to the invoking
      environment.
