pping.py

[Skaperen]

i wrote this command-line interface script to do multiple pings in parallel:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from __future__ import absolute_import, division, print_function, unicode_literals
"""Ping multiple IP addresses in parallel.

file          pping.py
name          pping - parallel ping
purpose       Ping multiple IP addresses in parallel
email         10054452614123394844460370234029112340408691

The intent is that this command works correctly under both Python 2 and
Python 3.  Please report failures or code improvement to the author.
