有没有办法纯粹在 .bat 文件中做到这一点?
目的是启动iexplore.exe
,然后在它完成时杀死那个实例。
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
以更改它。修改cmd
以更改运行的命令。
如果你想要一个杀死它的 stop.cmd,它看起来像这样
@echo off
for /F %%i in (%~dsp0MyProg.pid) do taskkill /F /PID %%i
del %~dsp0MyProg.pid
您可以使用 vbscript,这是一个创建记事本的示例,然后使用其 pid 终止它
strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set objStartup = objWMIService.Get("Win32_ProcessStartup")
Set objConfig = objStartup.SpawnInstance_
Set objProcess = GetObject("winmgmts:root\cimv2:Win32_Process")
errReturn = objProcess.Create("notepad.exe", null, objConfig, PID)
If errReturn = 0 Then
WScript.Echo "Process ID is: " & PID
End If
WScript.Echo "Ready to kill process: " & PID & "? [Y|y]"
Do While Not WScript.StdIn.AtEndOfLine
strInput = strInput & WScript.StdIn.Read(1)
Loop
If LCase(strInput) = "y" Then
WScript.Echo "Select * from Win32_Process Where ProcessId = '" & PID & "'"
Set colProcessList = objWMIService.ExecQuery("Select * from Win32_Process Where ProcessId = '" & PID & "'")
For Each objProcess in colProcessList
objProcess.Terminate()
Next
End If
另存为 myscript.vbs 并在命令行上
c:\test> cscript /nologo myscript.vbs
大多数情况下,您确实知道要开始什么任务——在这种情况下,iexplorer 将显示哪个页面。
那么怎么样
taskkill /FI "Windowtitle eq *yourpagetitle*"
它会杀死显示页面标题的所有实例,但是对于特定标题,通常应该只有一个。

@kybernetikos 提供的答案略有不同,因为它存在解析问题。注意线if %%j gr 0 (
@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 %%j gtr 0 (
set pid=%%j
)
)
echo %pid% > MyProg.pid
出于某种原因,您获取进程 id 的方法对我不起作用,但由于我是批处理方面的专家,所以我编写了自己的方法,附在此处:
@echo off
call:AsyncCmd
rem call:AsyncCmd "echo hello world"
rem call:AsyncCmd "call build.bat"
exit /b
rem ------------------------------------------------------------------------------------------
rem Starts asynchronous command execution
rem %1 is command, if empty - only aborts existing build.
rem ------------------------------------------------------------------------------------------
:AsyncCmd
if exist %~dp0SetupBuild_Completed.txt (
del /f %~dp0SetupBuild_Pid.txt >nul 2>&1
del /f %~dp0SetupBuild_Completed.txt >nul 2>&1
)
if not exist %~dp0SetupBuild_Pid.txt goto lStartProc
rem --------------------------------------------------
rem Abort build process
rem --------------------------------------------------
set /p pid=<%~dp0SetupBuild_Pid.txt
echo Cancelling setup build process, process id %pid%
pskill -t %pid%
del /f %~dp0SetupBuild_Pid.txt >nul 2>&1
:lStartProc
if "%~1" == "" exit /b 0
rem --------------------------------------------------
rem Starts asyncronous build process
rem --------------------------------------------------
set dir=%~dp0
set dir=%dir:~0,-1%
for /f "tokens=2 delims==; " %%a in ('wmic process call create "cmd /c mincon.exe && %~1 && echo 1>%~dp0SetupBuild_Completed.txt"^, "%dir%" ^| findstr /r "ProcessId"') do set pid=%%a
echo Setup build started, process id: %pid%
echo %pid%>%~dp0SetupBuild_Pid.txt
exit /b 0
我认为你不能用简单的命令行实用程序来做到这一点,因为 IE 实际上会为每个选项卡生成子进程,即如果 IE 尚未运行,你将获得一个父 IE 进程和一个用于选项卡的子进程,如果 IE 是已经在运行你只会得到一个子进程。
当你编写自己的工具来杀死 IE 时甚至会非常棘手,因为当你杀死一个子(选项卡)进程时,IE 会自动恢复这个选项卡。
另请参阅此相关问题:如何获取新创建的 IE8 窗口的进程?(尽管那里没有好的答案)。
PowerShell 可用于此:
powershell -executionPolicy bypass -command "& {$process = start-process $args[0] -passthru -argumentlist $args[1..($args.length-1)]; exit $process.id}" notepad test.txt
echo Process ID of new process: %errorlevel%
