Process command using python

Question

I want to pick up the command and its arguments in Python.

I can use

process=os.popen('ps -elf').read().split("\n")

and then use regular expression to extract the command but its ugly.

psutils returns a process name but not the actual commands and arguments

Is there a simple way to do this?

Answer 1

psutil can get the command line arguments:

import psutil

for p in psutil.process_iter():
    cmd_line = p.cmdline()
    if cmd_line:
        print(cmd_line)

EDIT: updated to fix the issue found by @Keir

Answer 2

The last suggestion is almost correct. It should be

for p in psutil.process_iter():
   cline = p.cmdline
   if cline: print(cline)
