I'm having a problem with subprocess.Popen when args parameter is given as sequence.
For example:
import subprocess
maildir = "/home/support/Maildir"
This works (it prints the correct size of /home/support/Maildir dir):
size = subprocess.Popen(["du -s -b " + maildir], shell=True,
stdout=subprocess.PIPE).communicate()[0].split()[0]
print size
But, this doesn't work (try it):
size = subprocess.Popen(["du", "-s -b", maildir], shell=True,
stdout=subprocess.PIPE).communicate()[0].split()[0]
print size
What's wrong?
