exit(...)
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.
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
