Question

在以下代码中，如果发现正在运行，我想终止ABClient.exe和ABClientMonitor.exe。但是，在尝试运行代码时，我收到Unexpected use of (错误

代码：

@echo off
color 0b
:loop
tasklist | find /i "ABClient.exe" > nul
set processFound1=%errorlevel%
tasklist | find /i "ABClientMonitor.exe" > nul
set processFound2=%errorlevel%
if %processFound1% == 0 (
    echo ABClient has been detected. Terminating...
    taskkill /f /im "ABClient.exe" > nul
    set process1lvl=%errorlevel%
    if %process1lvl% == 0 (
        echo ABClient has been terminated successfully!
        goto loop2
    ) ELSE (
        echo Failed to terminate ABClient!
        goto loop2
    )
)
:loop2
if %processFound2% == 0 (
    echo ABClientMonitor has been detected. Terminating...
    taskkill /f /im "ABClientMonitor.exe" > nul
    set process2lvl=%errorlevel%
    if %process2lvl% == 0 (
        echo ABClientMonitor has been terminated successfully!
        goto loop
    ) ELSE (
        echo Failed to terminate ABClientMonitor!
    goto loop
    )
)

在括号内声明的变量需要通过延迟扩展来调用，否则它们实际上不存在。在这种情况下，由于%process1lvl%和%process2lvl%变量的位置，您的内部if语句会计算为if == 0 (，这会导致语法错误。

要更正此问题，请将行setlocal enabledelayedexpansion添加到脚本的开头，并将%process1lvl%替换为!process1lvl!，并将%process2lvl%替换为!process2lvl!。

@echo off
setlocal enabledelayedexpansion
color 0b
:loop
tasklist | find /i "ABClient.exe" > nul
set processFound1=%errorlevel%
tasklist | find /i "ABClientMonitor.exe" > nul
set processFound2=%errorlevel%
if %processFound1% == 0 (
    echo ABClient has been detected. Terminating...
    taskkill /f /im "ABClient.exe" > nul
    set process1lvl=!errorlevel!
    if !process1lvl! == 0 (
        echo ABClient has been terminated successfully!
        goto loop2
    ) ELSE (
        echo Failed to terminate ABClient!
        goto loop2
    )
)
:loop2
if %processFound2% == 0 (
    echo ABClientMonitor has been detected. Terminating...
    taskkill /f /im "ABClientMonitor.exe" > nul
    set process2lvl=!errorlevel!
    if !process2lvl! == 0 (
        echo ABClientMonitor has been terminated successfully!
        goto loop
    ) ELSE (
        echo Failed to terminate ABClientMonitor!
    goto loop
    )
)
