Windows – How to disown/detach a process from the Git Bash terminal that come with Git’s Windows installer

bashgitgit-bashmingwwindows

I would like to run commands from the terminal (mostly Python servers) and essentially daemonize them. I am running the MinGW terminal "Git Bash" that comes with the Windows installer for Git.

Things tried that do not work:

  • nohup -> command not found
  • setsid -> command not found
  • $ script.py & -> does not behave as expected
  • $ script.py & disown -> does not behave as expected

I would use bg, but my end-goal is to close the terminal after my servers are all running and not kill the processes.

This is a synthesis from my longer answer to a similar question in SO.

If your app logs to stdout/stderr, use: 

cmd //c start cmd //k  "path\\to\\script-dir\\script.py"

If it logs to files, via sockets etc. and you do not need stdout/stderr, use: 

cmd //c start //D "path\\to\\script-dir" script.py

In both cases you get a daemon like process which will survive when you close bash. In the first instance your script is hosted in a visible cmd.exe window.
