Reload,求大神注释

#!/bin/sh
ls /etc/rc.d | while read a; do /etc/rc.d/$a; done
sleep 1
launchctl unload $(ls /System/Library/LaunchDaemons/ | grep -v logd | grep -v fud | grep -v ReportCrash | while read a; do printf /System/Library/LaunchDaemons/$a\ ; done)
launchctl unload /System/Library/NanoLaunchDaemons
sleep 1
launchctl load /Library/LaunchDaemons
launchctl load /System/Library/LaunchDaemons
launchctl load /System/Library/NanoLaunchDaemons

exit 0

这是在yalu102的reload中扒下来的代码,大神可否来个注释????

注释????

这几行代码是什么意思,大致上?

自己看看launchctl的帮助不就知道了
