让系统开机、关机运行程序的源码，运行一次后无需调用本身，也无需调用其他程序，可以让系统在开机关机时候自动运行程序。这里给出的范例是让系统自动记录开关机时间。-Let the system reboot, shutdown of the source code running the program, run once without calling itself, but also the need to call other programs, you can let the system a

点击一个按钮就可以让系统自己记录开关机时间，运行后不用再运行本程序，并且无需运行其他程序即可完成。程序的这个思路可以扩展到很多方面，如特定的程序在开机、关机时候运行~不能拿来做坏事哦~ 奉上源码-The click of a button you can switch the system record their own time machine, running no longer run the program, and no other programs running to compl
