Run a command continously (Reloads a command/program if it crashes)

runner.py

#!/usr/bin/env python
import signal
import sys
import os
import subprocess
process = 0

if len(sys.argv[:])<2:
  print "USAGE: python runner.py \"<your execution statement>\" \nQuotes are only necessary of you want to do redirection or something like that"
else:
  while(True):
    cmd = ' '.join(sys.argv[1:])
    print("Launching APP - " + cmd)
    process = subprocess.Popen(cmd, shell=True)
    process.communicate()

Usage

> python runner.py ./my_infinitely_running_app --argformyapp

Everything after runner.py will be executed indefinitely(until Ctrl-C is pressed). If the command ends/crashes, it will be reloaded.

sysout for the command will be sent to the parent scripts sysout
