我提出的另一种可能，不需要保存文件，灵感来自于使用grep:

tasklist /fi "ImageName eq MyApp.exe" /fo csv 2>NUL | find /I "myapp.exe">NUL
if "%ERRORLEVEL%"=="0" echo Program is running

/fi ""定义了一个应用程序的过滤器，在我们的例子中，它是*.exe名称 CSV定义了输出格式，CSV是必需的，因为默认情况下，如果可执行文件的名称太长，它可能会被截断，从而无法被稍后的find匹配。 find /I表示不区分大小写的匹配，可以省略

有关整个语法，请参阅tasklist命令的手册页。

TrueY的回答似乎是最优雅的解决方案，然而，我不得不瞎折腾一番，因为我不明白到底发生了什么。我先把问题讲清楚希望能给下一位同学节省点时间。

TrueY修改后的答案:

::Change the name of notepad.exe to the process .exe that you're trying to track
::Process names are CASE SENSITIVE, so notepad.exe works but Notepad.exe does NOT
::Do not change IMAGENAME
::You can Copy and Paste this into an empty batch file and change the name of
::notepad.exe to the process you'd like to track
::Also, some large programs take a while to no longer show as not running, so
::give this batch a few seconds timer to avoid a false result!!

@echo off
SETLOCAL EnableExtensions

set EXE=notepad.exe

FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto ProcessFound

goto ProcessNotFound

:ProcessFound

echo %EXE% is running
goto END
:ProcessNotFound
echo %EXE% is not running
goto END
:END
echo Finished!

不管怎样，我希望这对你们有帮助。我知道，如果你像我一样是新手，阅读批处理/命令行有时会有点困惑。

我使用PV.exe从http://www.teamcti.com/pview/prcview.htm安装在程序文件\PV与这样的批处理文件:

@echo off
PATH=%PATH%;%PROGRAMFILES%\PV;%PROGRAMFILES%\YourProgram
PV.EXE YourProgram.exe >nul
if ERRORLEVEL 1 goto Process_NotFound
:Process_Found
echo YourProgram is running
goto END
:Process_NotFound
echo YourProgram is not running
YourProgram.exe
goto END
:END

我需要一个重试的解决方案。这段代码将一直运行，直到找到进程，然后将其终止。你可以设置一个超时或任何你喜欢的东西。

注:

“。exe”是必选项 你可以让一个文件运行参数，版本如下

    :: Set programm you want to kill
    :: Fileextension is mandatory
    SET KillProg=explorer.exe

    :: Set waiting time between 2 requests in seconds
    SET /A "_wait=3"

    :ProcessNotFound
        tasklist /NH /FI "IMAGENAME eq %KillProg%" | FIND /I "%KillProg%"
        IF "%ERRORLEVEL%"=="0" (
            TASKKILL.EXE /F /T /IM %KillProg%
        ) ELSE (
            timeout /t %_wait%
            GOTO :ProcessNotFound
        )

taskkill.bat:

    :: Get program name from argumentlist
    IF NOT "%~1"=="" (
        SET "KillProg=%~1"
    ) ELSE (
        ECHO Usage: "%~nx0" ProgramToKill.exe & EXIT /B
    )

    :: Set waiting time between 2 requests in seconds
    SET /A "_wait=3"

    :ProcessNotFound
        tasklist /NH /FI "IMAGENAME eq %KillProg%" | FIND /I "%KillProg%"
        IF "%ERRORLEVEL%"=="0" (
            TASKKILL.EXE /F /T /IM %KillProg%
        ) ELSE (
            timeout /t %_wait%
            GOTO :ProcessNotFound
        )

使用。\taskkill.bat ProgramToKill.exe运行

TASKLIST | FINDSTR ProgramName || START "" "Path\ProgramName.exe"

基于vtrz的回答和Samuel Renkert关于另一个主题的回答，我想出了以下脚本，如果它还没有运行，则只运行%EXEC_CMD%:

@echo off
set EXEC_CMD="rsync.exe"
wmic process where (name=%EXEC_CMD%) get commandline | findstr /i %EXEC_CMD%> NUL
if errorlevel 1 (
    %EXEC_CMD% ...
) else (
    @echo not starting %EXEC_CMD%: already running.
)

如前所述，这需要管理特权。
