Question

Is there a way, I can execute in python a bash command with expansion: *

I tried thousand ways with no luck.

Actually I want to have a python script which enters each directory in the current dir, and executes a given bash command there (possibly a bash command with an expansion: *).

Answer 1

import os
from subprocess import check_call

cmd = 'echo *' # some shell command that may have `*`
for dirname in filter(os.path.isdir, os.listdir(os.curdir)):
    check_call(cmd, shell=True, cwd=dirname)

• filter(os.path.isdir, os.listdir(os.curdir)) lists all subdirectories of the current directory including those that starts with a dot (.)
• shell=True executes command given as cmd string through the shell. * if present is expanded by the shell as usual
• cwd=dirname tells that the command should be executed in dirname directory
