Run shell script from python

Question

I am trying to run a shell script from a python script using the following:

from subprocess import call call(['bash run.sh']) 

This gives me an error, but I can successfully run other commands, for example:

 call(['ls']) 

Answer 1

You must separate the arguments:

 call(['bash', 'run.sh']) call(['ls','-l']) 

Answer 2

 from subprocess import call import shlex call(shlex.split('bash run.sh')) 

You want to properly marc your team arguments. shlex.split() will do it for you.

Note. shlex.split () can be useful in determining the correctness of tokenization for args, especially in complex cases:

Answer 3

When you call call() with list , it expects each item in this list to match a command line argument. In this case, it searches for bash run.sh as an executable file with spaces and just as one line.

Try one of the following:

 call("bash run.sh".split()) call(["bash", "run.sh"])
