Run linux command in python 3

Running the following command in linux bash succeeds:

gimp --no-interface -b '(python-fu-scale RUN-NONINTERACTIVE 0 0 "img.jpg")' -b '(gimp-quit 0)'

Output:

batch command executed successfully

is printed and child process exits

Running it with python3.5 fails:

import subprocess
subprocess.run("gimp --no-interface -b '(python-fu-scale RUN-NONINTERACTIVE 0 0 \"img.jpg\")' -b '(gimp-quit 0)'".split())

results in output:

batch command executed successfully
batch command executed successfully

and the child process is stuck.

I'm not sure what's the difference and how to achieve equivalent behaviour in python. Is there a way to run bash command as string?

Solution

  • Using the following source - Calling an external command in Python helped to find an answer

    import subprocess
import shlex
subprocess.run(shlex.split("gimp --no-interface -b '(python-fu-scale RUN-NONINTERACTIVE 0 0 \"img.jpg\")' -b '(gimp-quit 0)'"))
