值得一提的是，如果你的任务名称非常长，那么它将不会完整地出现在任务列表结果中，所以它可能会更安全(而不是本地化)。

这个答案的变体:

:: in case your task name is really long, check for the 'opposite' and find  the message when it's not there
tasklist /fi "imagename eq yourreallylongtasknamethatwontfitinthelist.exe" 2>NUL | find /I /N "no tasks are running">NUL
if "%errorlevel%"=="0" (
    echo Task Found
) else (
    echo Not Found Task
)

如果你有多个同名的。exe文件，你只想检查其中一个(例如，你关心的是C:\MyProject\bin\release\MyApplication.exe而不是C:\MyProject\bin\debug\MyApplication.exe)，那么你可以使用以下方法:

@echo off

set "workdir=C:\MyProject\bin\release"
set "workdir=%workdir:\=\\%"

setlocal enableDelayedExpansion
for /f "usebackq tokens=* delims=" %%a in (`
    wmic process  where 'CommandLine like "%%!workdir!%%" and not CommandLine like "%%RuntimeBroker%%"'   get CommandLine^,ProcessId  /format:value
`) do (
    for /f "tokens=* delims=" %%G in ("%%a")  do (
        if "%%G" neq "" (
rem            echo %%G
            set "%%G"
rem            echo !ProcessId!
            goto :TheApplicationIsRunning
        )
    )
) 

echo The application is not running
exit /B

:TheApplicationIsRunning
echo The application is running
exit /B

在Windows下，您可以使用Windows管理规范(WMI)来确保没有带有指定命令行的应用程序被启动，例如:

Wmic进程where (name="nmake.exe") get commandline | findstr /i /c:"/f load. exe"Mak“/c:”/f build。编译已经开始了!> %ALREADY_STARTED & exit /b 1)

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。

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。

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