how do I get the process list in Python?

Question

How do I get a process list of all running processes from Python, on Unix, containing then name of the command/process and process id, so I can filter and kill processes.

Answer 1

On Linux, with a suitably recent Python which includes the subprocess module:

from subprocess import Popen, PIPE

process = Popen(['ps', '-eo' ,'pid,args'], stdout=PIPE, stderr=PIPE)
stdout, notused = process.communicate()
for line in stdout.splitlines():
    pid, cmdline = line.split(' ', 1)
    #Do whatever filtering and processing is needed

You may need to tweak the ps command slightly depending on your exact needs.
