I'm wondering why you not just use an init script or systemd service unit to start/stop/restart your app?

If you want to start a process (event in the foreground) and leave it running while you detatch, and come back later to the same session, then tmux is the way to go. You can learn enough tmux to be dangerous in ten minutes. The only features of ti that i use are window splitting, session detach, and session attach.

The conclusion is that if huponexit is set to false we can simply run processes in background appending & at the end of the command line.

If you close the terminal, you lose job control. If you use tmux, you can close the terminal, but leave the session running, and reattach to the session later. It is well work looking into.

I've ended up using Plackup to start the catalyst app's psgi script (still via fast cgi), and I'm using -r to indicate it should watch for changes, and reload the server when changes are detected. It does this fine, as long as my commandline terminal is still open. The moment I close it, the server continues to run, yet any watching for changes, killing, and restarting no longer happens (as far as I can tell). Is there any way to get Plack's scripts that watch and reload (i.e. Restarter.pm, etc), to continue to run after I close OSX's terminal window

end the SSH session?
