#!/bin/bash
# Mac OS launchctl utility
# Support partial match
# Will exit on error if no of more than one service is found.

# @link https://gist.github.com/lavoiesl/6160897
# 
# Usage:
#   service selfupdate
#       update from the Gist
#   service php
#       searches for a plist containing 'php'
#   service php load|unload|reload
#       insert or remove a plist from launchctl
#   service php start|stop|restart
#       manage a daemon, but leave it in launchctl  (does not work with Agents)
#   service php link
#       If you use Homebrew, which you should, it will link the plist of this Formula into ~/Library/LaunchAgents, reloading if needed.
#       Very useful when upgrading.

Hello, great script but load daemons at startup and no way to force load -F and unload -w args.
