               1 Dir(s)  243,993,673,728 bytes free

What am i doing wrong here

`check_output(cmd, shell=True)`. Subprocess is not aware of `*`. Shell is. — Łukasz Rogalski, Apr 14 '16 at 12:54

And if You write full, correct name in Your path instead of wildcard? still not working, have You tried? If still want to use it look at this answer: Python subprocess wildcard usage

Thanks for the answer its an enlightenment for me :) – jhon.smith Apr 14 '16 at 13:07
Sorry, I was not clear enough but what I mean is if it does not work only with wildcard or at all? That info makes difference in looking for solution :) and by the wildcard usage says exactly You to use shell=True :), but before using that answer has to be sure it works at all :) – Drako Apr 14 '16 at 13:35
