如何检查应用程序是否从批处理(好cmd)文件运行?
如果程序已经在运行，我不需要启动另一个实例。(我不能改变应用程序，使它只有单一实例。)
此外，应用程序可以作为任何用户运行。

我喜欢WMIC和TASKLIST工具，但是在windows的家庭/基本版本中没有。另一种方法是在几乎所有windows机器上使用QPROCESS命令(对于那些有终端服务的机器-我认为只有XP没有SP2，所以几乎所有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命令没有TASKLIST那么强大，只能显示12个进程名符号，但如果TASKLIST不可用，则应考虑使用QPROCESS命令。
更简单的用法，它使用进程名作为参数(在这种情况下，当你传递可执行名称时，.exe后缀是必选的):
@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
QPROCESS的两种使用方式的区别是，QPROCESS *将列出所有进程，而QPROCESS some.exe将仅为当前用户过滤进程。
通过windows脚本主机exe而不是WMIC使用WMI对象也是一种选择。它还应该在每台windows机器上运行(不包括关闭WSH的机器，但这种情况很少见)。下面是一个通过WMI类列出所有进程的bat文件，可以用来代替上面脚本中的QPROCESS(它是jscript/bat的混合体，应该保存为.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 );
}
以及检查进程是否正在运行的修改:
@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TASKLIST的机器上使用。
最终的技术是使用MSHTA。这将运行在每一台windows机器从XP和以上，不依赖于windows脚本主机设置。调用MSHTA可能会降低一些性能(同样应该保存为bat):
@if (@X)==(@Y) @end /* JSCRIPT COMMENT **
@echo off
setlocal

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

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。
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
我通常在cmd提示符下执行以下命令来检查我的program.exe是否正在运行:
tasklist | grep program
