检查进程是否正在运行？

Question

我想检查进程是否正在运行？ 如果该进程未运行，则执行它（在本示例中，我使用进程名称 = calc.exe 的计算器） 我启动了批处理脚本，但我相信有语法问题！

@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

Answer 1

这是使用您的代码作为基础的另一种方法：

@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

Answer 2

你可以这样尝试：

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

好吧，我还找到了另一种方法来实现连续检查（循环）进程“WinRAR.exe”的存在（作为要检查的应用程序的示例），因此我们当然可以更改要检查的路径和进程名称。

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

If not errorlevel 1 (Echo "%MyProcess%" est en cours d^'execution) else (start "" "%MyApplication%")
ping -n 60 127.0.0.1 >nul 
goto start

Answer 5

我最近做了类似的事情，当我只想打开一个应用程序时，如果它的进程尚不存在。

TASKLIST | FINDSTR myProgram
if %ERRORLEVEL% neq 0 ("your conditions here")

您可以检查任务列表中是否有程序。如果任务列表中的 Findstr 在任务列表中，则会返回错误级别 0。您可以在检查后利用它来构建您的条件。

TASKLIST | FINDSTR git-bash || START "" "C:\Program Files\Git\git-bash.exe"

^ 以上是我的一行解决方案，用于在还没有实例的情况下打开 git-bash。
