Here is a bash command that I want to run from a python
program: sudo grep "^user\:" /etc/shadow
If I enter the command directly into a terminal it works
perfectly. If I run it from a python program it returns an
empty string. Below is the code I am using. Suggestions
appreciated.
cmdlist = ["sudo", "grep", '"^$USER\:"', "/etc/shadow"]
p = subprocess.Popen(cmdlist,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
shadow, err = p.communicate()
print shadow
