exit(*args) public 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. true and FALSE of status means success and failure respectively. The interpretation of other integer values are system dependent.
begin exit puts "never get here" rescue SystemExit puts "rescued a SystemExit exception" end puts "after begin block"
produces:
rescued a SystemExit exception after begin block
Just prior to termination, Ruby executes any at_exit functions (see Kernel::at_exit) and runs any object finalizers (see ObjectSpace::define_finalizer).
at_exit { puts "at_exit function" } ObjectSpace.define_finalizer("string", proc { puts "in finalizer" }) exit
produces:
at_exit function in finalizer
