从命令行启动进程时，如何捕获进程的PID? [英] How to capture the PID of a process when launching it from command line?

问题描述

是否有一种方法可以纯粹在.bat文件中执行此操作?

Is there a way to do this purely in a .bat file?

目的是启动iexplore.exe，然后在完成后杀死该实例.

The purpose is to launch iexplore.exe, then kill just that instance when it's finished.

推荐答案

这是我使用的:

@echo off

rem there is a tab in the file at the end of the line below
set tab=    
set cmd=javaw -jar lib\MyProg.jar
set dir=%~dp0

echo Starting MyProg
set pid=notfound

for /F "usebackq tokens=1,2 delims=;=%tab% " %%i in (
    `wmic process call create "%cmd%"^, "%dir%"`
) do (
    if /I %%i EQU ProcessId (
        set pid=%%j
    )
)

echo %pid% > MyProg.pid

该目录设置为cmd文件所在的目录.更改dir进行更改.修改cmd以更改运行哪个命令.

The directory is set to the directory that the cmd file is located in. Change dir to alter that. Modify cmd to change which command is run.

如果您想要一个stop.cmd杀死它，它将看起来像这样

If you want a stop.cmd that kills it, it would look like this

@echo off
for /F %%i in (%~dsp0MyProg.pid) do taskkill /F /PID %%i
del %~dsp0MyProg.pid
