How to get process status using pid?

问题:

If I known a process's pid, how can I tell if the process is an zombie using Python ?

回答1:

You could use a the status feature from psutils:

import psutil p = psutil.Process(the_pid_you_want) if p.status == psutil.STATUS_ZOMBIE:     .... 

回答2:

here's a quick hack using procfs (assuming you're using Linux):

def procStatus(pid):     for line in open("/proc/%d/status" % pid).readlines():         if line.startswith("State:"):             return line.split(":",1)[1].strip().split(' ')[0]     return None 

this function should return 'Z' for zombies.
