#!/usr/bin/env python import os import sys

Detach from the controlling terminal and parent process by forking twice to daemonize ourselves,

then run the command passed as argv[1]. Send log data to argv[2].

pid = os.fork() if (pid == 0): os.setsid() pid = os.fork() if (pid != 0): os._exit(0) else: sys.exit()

si = file(os.devnull, 'r') so = file(sys.argv[2], 'w') se = so

Replace those fds with our own

os.dup2(si.fileno(), sys.stdin.fileno()) os.dup2(so.fileno(), sys.stdout.fileno()) os.dup2(se.fileno(), sys.stderr.fileno())

ret = os.system(sys.argv[1])

os._exit(ret)
