if you expect one line of output, why are you doing readlines()[1] ?
>>> f = subprocess.Popen("set | grep IFS", shell=True,
>>> f.stdout.readlines()[1]
Traceback (most recent call last):
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IndexError: list index out of range
this works for me:
>>> f = subprocess.Popen("set | grep IFS", shell=True,
stdout=subprocess.PIPE)
>>> f.stdout.readlines()
["IFS=$' \\t\\n'\n"]
what does the above return on your machine?
