windows下bat批处理实现守护进程

实现：

检查是否有notepad，要用的话就算成自己的进程名，如果进程宕了就过会自动重启（会在当前目录下生成一个start.bat）

 

@echo off

set _task=notepad.exe
set _svr=c:\windows\notepad.exe
set _des=start.bat

:checkstart
;for /f "tokens=5" %%n in ('qprocess.exe ^| find "%_task%" ') do (
; if %%n==%_task% (goto checkag) else goto startsvr
;)

;改成

SET status=1 
(TASKLIST|FIND /I "%_task%"||SET status=0) 2>nul 1>nul
ECHO %status%
IF %status% EQU 1 (goto checkag ) ELSE (goto startsvr)

:startsvr
echo %time% 
echo ********程序开始启动********
echo 程序重新启动于 %time% ,请检查系统日志 >> restart_service.txt
echo start %_svr% > %_des%
echo exit >> %_des%
start %_des%
set/p=.<nul
for /L %%i in (1 1 10) do set /p a=.<nul&ping.exe /n 2 127.0.0.1>nul
echo .
echo Wscript.Sleep WScript.Arguments(0) >%tmp%\delay.vbs 
cscript //b //nologo %tmp%\delay.vbs 10000 
del %_des% /Q
echo ********程序启动完成********
goto checkstart

:checkag
echo %time% 程序运行正常,10秒后继续检查.. 
echo Wscript.Sleep WScript.Arguments(0) >%tmp%\delay.vbs 
cscript //b //nologo %tmp%\delay.vbs 10000 
goto checkstart
