python中写shell,亲测可用，转自stackoverflow
To run a bash script, copy from stackoverflow
def run_script(script, stdin=None):
"""Returns (stdout, stderr), raises error on non-zero return code"""

# arguments are passed in exactly this order (spaces, quotes, and newlines won't
# cause problems):

stdout=subprocess.PIPE, stderr=subprocess.PIPE,
stdin=subprocess.PIPE)
stdout, stderr = proc.communicate()
