Batch file 意外使用（批处理文件）

在下面的代码中，如果发现正在运行，我想终止

ABClient.exe

和

ABClientMonitor.exe

。但是，当尝试运行代码时，我得到了一个

意外使用（

错误

代码：

---

括号内声明的变量需要用延迟扩展调用，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，内部

if

语句的计算结果为

if==0（

，这会导致语法错误

要更正此问题，请在脚本开头添加行

setlocal enabledelayedexpansion

，并将

%process1lvl%

替换为

！process1lvl！

，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
    )
)

谢谢！只是想知道，如果一个变量在一个括号内-在一个括号内，我会怎么做。它还会是吗！变量！？是的，任何时候一个变量至少在一组括号内，你都需要延迟展开，否则变量的值将不会更新。

@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
    )
