Linux – Run a python script that is never Killed

Aha, I've found the answer myself.

In PowerShell, scripts to be executed need to be proceeded by ".\"

So, "PS > script.py" doesn't work, but "PS > .\script.py" does.

Also, using this syntax adding ".py" to PATHEXT works fine under PowerShell.

Have a look at reptyr, which does exactly that. The github page has all the information.

reptyr - A tool for "re-ptying" programs.

reptyr is a utility for taking an existing running program and attaching it to a new terminal. Started a long-running process over ssh, but have to leave and don't want to interrupt it? Just start a screen, use reptyr to grab it, and then kill the ssh session and head on home.

USAGE

reptyr PID

"reptyr PID" will grab the process with id PID and attach it to your current terminal.

After attaching, the process will take input from and write output to the new terminal, including ^C and ^Z. (Unfortunately, if you background it, you will still have to run "bg" or "fg" in the old terminal. This is likely impossible to fix in a reasonable way without patching your shell.)
