Keep perl script running after ssh disconnect

Question

Is there a native way to keep a perl script running on a server(uninterrupted by ssh disconnections) without the use of tools like tmux and screen ? I am using Ubuntu.

Answer 1

You can try the POSIX command nohup

Most shells also come with disown

As far as a perl native solution, you can simply use the signal handling features of perl.

$SIG{HUP} = sub {
  print "got SIGHUP\n";
};

Answer 2

screen is what you are looking for.
