Finding the command for a specific PID in Linux from Python

Question

I\'d like to know if it\'s possible to find out the \"command\" that a PID is set to. When I say command, I mean what you see in the last column when you run the command \"t

Answer 1

An interesting Python package is psutil.

For example, to get the command for a specific PID:

import psutil
pid = 1234 # The pid whose info you're looking for
p = psutil.Process(pid)
print p.cmdline

The last line will print something like ['/usr/bin/python', 'main.py'] .

A more robust way to get this information, being careful if the pid represents a process no longer running:

import psutil
pid = 1234 # The pid whose info you're looking for
if pid in psutil.get_pid_list():
    p = psutil.Process(pid)
    print p.cmdline
