Little brother has just started to get in touch with batch processing and wants to write a batch file. I've racked my brains and still can't figure it out. Please help from the experts.

Requirement: Automatically restart 30 seconds after booting. After restarting three times, the fourth time automatically delete its own file.

Little brother thanks everyone here in advance.

Put it in the startup directory. Automatically run every time it restarts, and redirect a :1 after itself. The batch script reads itself to judge the number of :1. If it reaches 3 times, delete itself.

Demo version Note, don't make a line break at the end, so that it's more convenient for digital calculation~

@echo off

call :count

if %a% lss 3 (set /p=+1>>%0<nul &echo,shutdown -r -t 30) else (echo,del %0)

pause

exit



:count

set /a a=0
