windows下切割移动nginx日志并删除几天前日志的bat脚

写一个下边的bat脚本，然后将bat加入系统执行计划即可。

@echo
taskkill /F /IM nginx.exe > nul
set homedir=D:\nginx-1.9.9
d:
cd %homedir%
rem date format：20191211

set today=%date:~0,4%%date:~5,2%%date:~8,2%
set /a yesterday=%today%-1
set logdir=%homedir%\logs\%yesterday%
md %dir%

rem access log 
move %homedir%\logs\*.log %logdir%\

start nginx

rem delete old logs dir
set /a deletedaydir=%today%-7
rd /s /q %homedir%\logs\%deletedaydir%
