这是我的批处理密码脚本，它在启动 cmd 或批处理文件时运行，但是当用户按下 ctrl-c 或 ctrl-break 时，它会绕过登录脚本

这是发生了什么我运行 cmd 它启动了所有工作但是当我按下 CTRL-C 时它退出并返回到正常的 CMD 所以你可以再弄乱 cmd 这应该是为了保护人们不要弄乱我的 cmd酷炫的风格

Answer 1

下面的批处理文件不能用 Ctrl-C 取消，如果用 Ctrl-Break 取消，cmd.exe 窗口将关闭，因此用户永远无法访问正常的 cmd.exe 命令行会话 通过这个批处理文件。

@echo off
setlocal

if "%~1" equ "NonCancelable" goto NonCancelable
start "" /B cmd /C "%~F0" NonCancelable
exit

:NonCancelable
echo You can NOT cancel me!
echo/
set "var="
set /P "var=Enter password (enter Exit to end): "
if /I "%var%" neq "exit" goto :NonCancelable
echo Terminating non cancelable...
pause
exit

Answer 2

我遇到了同样的问题。

当通过 ctrl+C 终止批处理脚本时，一个 cmd 会话会在 Bathscript 的 %CD% 目录处启动。我通过另一个批处理脚本启动批处理脚本解决了这个问题，如下所示：

::launcher
@ECHO off
CD "directory of the batch script"
batchscript.cmd
EXIT

当 batchscript.cmd 被 ctrl+C 终止时，它会返回到启动器，该启动器会因为 EXIT 语句而立即关闭

(以管理员身份运行时需要CD语句。这是因为批处理脚本的CD变量将等于C:\Windows\System32。但是如果批处理脚本的目录可以省略CD语句包含在 PATH 变量中）
