Answer 1

To emulate nohup in Python, you could make child processes to ignore SIGHUP signal:

import signal

def ignore_sighup():
    signal.signal(signal.SIGHUP, signal.SIG_IGN)

i.e., to emulate the bash script:

#!/bin/bash
for f in subdir/*.sh; do
    nohup "$f" "$@" &> /dev/null &
done

using subprocess module in Python:

#!/usr/bin/env python3
import sys
from glob import glob
from subprocess import Popen, DEVNULL, STDOUT

for path in glob('subdir/*.sh'):
    Popen([path] + sys.argv[1:], 
          stdout=DEVNULL, stderr=STDOUT, preexec_fn=ignore_sighup)

To create proper daemons, you could use python-daemon package.
