如果用户在退出前按 Ctrl+C 执行命令，则批处理脚本 [英] batch script if user press Ctrl+C do a command before exiting

问题描述

我写了一个脚本，开头是net use，结尾是net use/DELETE.

但如果用户决定按 Ctrl + C 并退出脚本，我需要执行 net use/DELETE.

这可能吗?我在谷歌上找不到任何东西.

解决方案

当然，只需在新的 CMD 会话中执行大部分脚本:

@echo offif "%~1" neq "_start_" (净使用...cmd/c "%~f0" _start_ %*净使用/删除...退出/b)移位/1REM 脚本的其余部分放在这里

只要您的控制台窗口保持打开状态，net use/delete 命令就会在内部 cmd 会话关闭后始终触发.它可能会因为正常运行、用户按下 Ctrl-C 或致命错误而关闭 - 最后的 net use delete 仍会触发.

I wrote a script which is doing net use at the beginning and net use /DELETE at the end.

But if user decides to press Ctrl + C and exits the script, I need to do a net use /DELETE.

Is that possible? I can't find anything on google.

解决方案

Sure, simply execute most of your script in a new CMD session:

@echo off
if "%~1" neq "_start_" (
  net use ...
  cmd /c "%~f0" _start_ %*
  net use /delete ...
  exit /b
)
shift /1
REM rest of script goes here

As long as your console window remains open, the net use /delete command will always fire after the inner cmd session closes. It could close because of normal run, user presses Ctrl-C, or fatal error - the final net use delete will still fire.
