Python: subprocess call with shell=False not working

Question

I am using Python script to invoke a Java virtual machine. The following command works:

subprocess.call([\"./rvm\"], shell=False)  # works
subprocess.call([\         


        

Answer 1

You need to split the commands into separate strings:

subprocess.call(["./rvm", "xyz"], shell=False)

A string will work when shell=True but you need a list of args when shell=False

The shlex module is useful more so for more complicated commands and dealing with input but good to learn about:

import shlex

cmd = "python  foo.py"
subprocess.call(shlex.split(cmd), shell=False)

shlex tut
