How to call a shell script from python code?

python shell

The subprocess module will help you out.

Blatantly trivial example:

>>> import subprocess>>> subprocess.call(['sh', './test.sh']) # Thanks @Jim Dennis for suggesting the []0 >>>

Where test.sh is a simple shell script and 0 is its return value for this run.

python shell

There are some ways using os.popen() (deprecated) or the whole subprocess module, but this approach

import osos.system(command)

is one of the easiest.

python shell

In case you want to pass some parameters to your shell script, you can use the method shlex.split():

import subprocessimport shlexsubprocess.call(shlex.split('./test.sh param1 param2'))

with test.sh in the same folder:

#!/bin/shecho $1echo $2exit 0

Outputs:

$ python test.py param1param2
