Curly Braces in python Popen

Question

Running subprocess won\'t handle curly braces correctly

# Python 2.7.4

import subprocess
subprocess.Popen(\'ls src/*.cpp\',shell=True): 
src/tonemap.cpp src         


        

Answer 1

The other machine uses a different shell that doesn't handle that syntax.

Answer 2

In your case, Popen executed correctly, error is reported from ls. It should give same error when you execute the command:

ls src/{t,p}*.cpp

in terminal.

Answer 3

shell=True runs /bin/sh that doesn't support this syntax. Specify bash explicitly:

from subprocess import check_call

check_call('ls src/{t,p}*.cpp', shell=True, executable='/bin/bash')
