The abort function does this  For example   abort  Message goes here     Note  the abort message will be written to STDERR as opposed to puts which will write to STDOUT

If you want to denote an actual error in your code  you could raise a RuntimeError exception   raise RuntimeError   Message goes here    This will print a stacktrace  the type of the exception being raised and the message that you provided  Depending on your users  a stacktrace might be too scary  and the actual message might get lost in the noise  On the other hand  if you die because of an actual error  a stacktrace will give you additional information for debugging

I ve never heard of such a function  but it would be trivial enough to implement     def die msg    puts msg   exit end   Then  if this is defined in some  rb file that you include in all your scripts  you are golden     just because it s not built in doesn t mean you can t do it yourself  -

I got here searching for a way to execute some code whenever the program ends  Found this   Kernel at exit   puts  sayonara      do whatever           call  exit or  abort or just let the program end   calling  exit  will skip the call   Called multiple times will register multiple handlers
