Windows 检查一个进程是否正在运行？

我想检查一个进程是否正在运行？ 如果进程没有运行，那么我就执行它（在这个例子中，我把计算器的进程名称=calc.exe）我启动了批处理脚本，但我有一个语法问题，我相信！

我想检查一个进程是否正在运行。

@echo off
Set MyProcess=calc.exe
echo %MyProcess%
pause
for /f "tokens=1" %%i In ('tasklist /NH /FI "imagename eq %MyProcess%"') do set ff=%%i
echo %ff%
If /i %ff%==%MyProcess% (Echo %ff% est en cours d^'execution) Else (Start %MyProcess%)
pause

这里有另一种以你的代码为基础的方法。

@echo off
Set "MyProcess=calc.exe"
echo "%MyProcess%"
tasklist /NH /FI "imagename eq %MyProcess%" 2>nul |find /i "%MyProcess%" >nul
If not errorlevel 1 (Echo "%MyProcess%" est en cours d^'execution) else (start "" "%MyProcess%")
pause

你可以这样试一试。

tasklist /FI "IMAGENAME eq calc.exe" 2>NUL | find /I /N "calc.exe">NUL
if "%ERRORLEVEL%"=="0" 
echo Running

我在Vbscript中的解决方案(°_^)。

Option Explicit
Dim ws,MyApplication,MyProcess
Set ws = CreateObject("WScript.Shell")
MyApplication = "%Programfiles%\WinRAR\WinRAR.exe"
MyProcess = "WinRAR.exe"
Do
'We check if the process is not running so we execute it
    If CheckProcess(MyProcess) = False then 
        Call Executer(DblQuote(MyApplication),0)'0 to Hide the console
'We made ​​a one-minute break and continue in our loop to check 
'whether or not our process exists(in our case = WinRAR.exe)
        Pause(1)
    End if
Loop
'***********************************************************************************************
Function CheckProcess(MyProcess)
    Dim strComputer,objWMIService,colProcessList
    strComputer = "."
    Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
    Set colProcessList = objWMIService.ExecQuery _
    ("Select Name from Win32_Process WHERE Name LIKE '" & MyProcess & "%'")
        If colProcessList.count > 0 then
            CheckProcess = MyProcess & " is running"
            CheckProcess = True
        else
            CheckProcess = MyProcess & " is not running"
            CheckProcess = False
        End if
    Set objWMIService = Nothing
    Set colProcessList = Nothing
End Function

        MyCmd = "CMD /C " & StrCmd & " "
        Resultat = ws.run(MyCmd,Console,True)
        If Resultat = 0 Then
        Else

好吧，我还找到了另一种方法来实现连续检查（在循环中）进程 "WinRAR.exe "的存在（作为检查应用程序的一个例子），所以我们当然可以改变检查的路径和进程名称。

@echo off
Set "MyApplication=%Programfiles%\WinRAR\WinRAR.exe"
Set "MyProcess=WinRAR.exe"
