如何通过批处理脚本检查进程是否正在运行

Question

如何从批处理(cmd)文件中检查应用程序是否正在运行？

如果程序已在运行,我不需要启动另一个实例.(我无法更改应用程序以使其仅为单个实例.)

该应用程序也可以像任何用户一样运行.

Answer 1

我想出的另一种可能性是受到grep的启发,它是:

tasklist /FI "IMAGENAME eq myapp.exe" 2>NUL | find /I /N "myapp.exe">NUL
if "%ERRORLEVEL%"=="0" echo Program is running

它不需要保存额外的文件,所以我更喜欢这种方法.

Answer 2

这是我如何解决的问题:

tasklist /FI "IMAGENAME eq notepad.exe" /FO CSV > search.log

FOR /F %%A IN (search.log) DO IF %%~zA EQU 0 GOTO end

start notepad.exe

:end

del search.log

如果尚未运行,上面将打开记事本.

编辑:请注意,这不会找到任务列表中隐藏的应用程序.这将包括以不同用户身份运行的任何计划任务,因为这些任务会自动隐藏.

我喜欢Chaosmaster的解决方案!但我寻找的解决方案无法启动另一个外部程序(如find.exe或findstr.exe).所以我从Matt Lacey的解决方案中添加了这个想法,它创建了一个可避免的临时文件.最后我找到了一个相当简单的解决方案,所以我分享了......

SETLOCAL EnableExtensions
set EXE=myprog.exe
FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto FOUND
echo Not running
goto FIN
:FOUND
echo Running
:FIN

这很适合我......

在Windows下,您可以使用Windows Management Instrumentation(WMI)确保没有启动具有指定命令行的应用程序,例如:

wmic process where (name="nmake.exe") get commandline | findstr /i /c:"/f load.mak" /c:"/f build.mak" > NUL && (echo THE BUILD HAS BEEN STARTED ALREADY! > %ALREADY_STARTED% & exit /b 1)

Answer 5

npocmaka使用QPROCESS代替TASKLIST的建议很棒但是,它的答案是如此之大和复杂,以至于我觉得有必要发布一个非常简化的版本,我想这将解决大多数非高级用户的问题:

QPROCESS "myprocess.exe">NUL
IF %ERRORLEVEL% EQU 0 ECHO "Process running"

上面的代码在Windows 7中进行了测试,用户具有管理员权限.

Answer 6

我使用安装在Program Files\PV中的http://www.teamcti.com/pview/prcview.htm中的PV.exe 和批处理文件,如下所示:

@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

Answer 7

TrueY的答案似乎是最优雅的解决方案,然而,我不得不做一些搞乱,因为我不明白到底发生了什么.让我清楚一点,希望为下一个人节省一些时间.

TrueY的修改答案:

::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!

无论如何,我希望有所帮助.我知道有时读书批处理/命令行有时会让你感到困惑,如果你像我这样的新手.

Answer 8

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

Answer 9

Matt Lacey提供的答案适用于Windows XP.但是,在Windows Server 2003中

 tasklist /FI "IMAGENAME eq notepad.exe" /FO CSV > search.log

回报

信息:没有正在运行的任务符合指定的条件.

然后在进程运行时读取.

我没有一堆批处理脚本的经验,所以我的搜索是在search.log文件中搜索进程名称并将结果泵入另一个文件并搜索任何输出.

tasklist /FI "IMAGENAME eq notepad.exe" /FO CSV > search.log

FINDSTR notepad.exe search.log > found.log

FOR /F %%A IN (found.log) DO IF %%~zA EQU 0 GOTO end

start notepad.exe

:end

del search.log
del found.log

我希望这有助于其他人.

我喜欢WMIC和TASKLIST工具，但是它们在QPROCESSWindows的家庭/基本版本中不可用。另一种方法是使用几乎每个Windows机器上都可用的命令（对于那些具有终端服务的机器-我认为只有Win XP才没有SP2，所以实际上Windows机器）：

@echo off
:check_process
setlocal
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running
set process_to_check=%~1
:: QPROCESS can display only the first 12 symbols of the running process
:: If other tool is used the line bellow could be deleted
set process_to_check=%process_to_check:~0,12%

QPROCESS * | find /i "%process_to_check%" >nul 2>&1 && (
    echo process %process_to_check%  is running
) || (
    echo process %process_to_check%  is not running
)
endlocal

QPROCESS该命令不那么强大，TASKLIST并且只能显示进程名称的12个符号，但如果TASKLIST不可用，则应予以考虑。

如果将进程用作参数，则使用名称更简单的用法（.exe在这种情况下，如果您传递可执行文件名称，则后缀是必需的）：

@echo off
:check_process
setlocal
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running
:: .exe suffix is mandatory
set "process_to_check=%~1"


QPROCESS "%process_to_check%" >nul 2>&1 && (
    echo process %process_to_check%  is running
) || (
    echo process %process_to_check%  is not running
)
endlocal

两种QPROCESS使用方式之间的区别在于，QPROCESS *会列出所有进程，而QPROCESS some.exe只会为当前用户过滤进程。

WMI通过Windows脚本宿主exe而不是使用对象WMIC也是一种选择。它也应该在每台Windows机器上运行（不包括关闭WSH的机器，但这是一种罕见的情况）.bat文件通过WMI列出了所有进程类，并且可以代替QPROCESS上面的脚本使用（它是jscript / bat混合体，应另存为.bat）：

@if (@X)==(@Y) @end /* JSCRIPT COMMENT **


@echo off
cscript //E:JScript //nologo "%~f0"
exit /b

************** end of JSCRIPT COMMENT **/


var winmgmts = GetObject("winmgmts:\\\\.\\root\\cimv2");
var colProcess = winmgmts.ExecQuery("Select * from Win32_Process");
var processes =  new Enumerator(colProcess);
for (;!processes.atEnd();processes.moveNext()) {
    var process=processes.item();
    WScript.Echo( process.processID + "   " + process.Name );
}

修改将检查进程是否正在运行：

@if (@X)==(@Y) @end /* JSCRIPT COMMENT **


@echo off
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running
set process_to_check=%~1

cscript //E:JScript //nologo "%~f0" | find /i "%process_to_check%" >nul 2>&1 && (
    echo process %process_to_check%  is running
) || (
    echo process %process_to_check%  is not running
)

exit /b

************** end of JSCRIPT COMMENT **/


var winmgmts = GetObject("winmgmts:\\\\.\\root\\cimv2");
var colProcess = winmgmts.ExecQuery("Select * from Win32_Process");
var processes =  new Enumerator(colProcess);
for (;!processes.atEnd();processes.moveNext()) {
    var process=processes.item();
    WScript.Echo( process.processID + "   " + process.Name );
}

这两个选项可以在没有的机器上使用TASKLIST。

最终的技术是使用MSHTA。这将在XP及以上版本的每台Windows计算机上运行，​​并且不依赖于Windows脚本主机设置。的调用MSHTA可能会降低一点性能（再次应保存为bat）：

@if (@X)==(@Y) @end /* JSCRIPT COMMENT **
@echo off

setlocal
if "%~1" equ "" echo pass the process name as forst argument && exit /b 1
:: first argument is the process you want to check if running

set process_to_check=%~1


mshta "about:<script language='javascript' src='file://%~dpnxf0'></script>" | find /i "%process_to_check%" >nul 2>&1 && (
    echo process %process_to_check%  is running
) || (
    echo process %process_to_check%  is not running
)
endlocal
exit /b
************** end of JSCRIPT COMMENT **/


   var fso= new ActiveXObject('Scripting.FileSystemObject').GetStandardStream(1);


   var winmgmts = GetObject("winmgmts:\\\\.\\root\\cimv2");
   var colProcess = winmgmts.ExecQuery("Select * from Win32_Process");
   var processes =  new Enumerator(colProcess);
   for (;!processes.atEnd();processes.moveNext()) {
    var process=processes.item();
    fso.Write( process.processID + "   " + process.Name + "\n");
   }
   close();

Answer 11

您应该检查父进程名称，请参阅有关基于 .NET 的解决方案的代码项目文章**。

一种非编程方式来检查：

1. 启动cmd.exe
2. 启动应用程序（例如，c:\windows\notepad.exe）
3. 在Process Explorer中检查 Notepad.exe 进程的属性
4. 检查父进程（这显示 cmd.exe）

可以通过获取父进程名称来检查同样的情况。
