nohup

11/08/2024

• Running a Python Script in the Background in Linux
• You can run the script with nohup which ignores the hangup signal. This means that you can close the terminal without stopping the execution. Also, don’t forget to add & so the script runs in the background:

    # test_handler.py

    from handler import EndpointHandler
    handler = EndpointHandler()
    for _ in range(100):

        (...)

        response = handler(
            data={
                "base_image": base_image,
                "material_image": material_image,
                "prompt_material": prompt_material,
                "seed": seed,
            }, 
        )
        
        (...)

    nohup python test_handler.py &



• The output will be saved .log file:

  
      nohup python test_handler.py > output.log &
      [1] 1729
  

  
  
• You can find the process and its process Id with this command:

  
      ps aux | grep test_handler.py
      root      1729 10.2  0.2 29499332 541108 pts/2 SNl  11:08   0:07 python test_handler.py
      root      3007  0.0  0.0   4032  2008 pts/2    S+   11:09   0:00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn --exclude-dir=.idea --exclude-dir=.tox test_handler.py
  

  
  
• You can kill it with the kill command with PID:

  
      kill 1729
