如何在超时时要求批处理文件用户输入 [英] How to ask for batch file user input with a timeout

问题描述

所以我试图在 set 命令下向我的 if 语句之一添加一个计时器，但我不确定该命令是什么.该脚本将启动并等待 30 分钟，然后重新启动 PC 或等待用户在那时输入或取消它.因此，我设置了立即重启"和取消"的两个 if 语句，但现在我需要一个 if 语句，让它从 30 分钟开始倒计时，然后再执行我的重启命令.此外，如果有人知道如何在那里添加一个可视化计时器来显示剩余的时间，那将是一个加号.谢谢各位！！！

So I am trying to add a timer to one of my if statements under a set command but I'm not sure what the command would be. The script will launch and wait thirty minutes before it reboots the PC or wait for a users input to input it at that time or cancel it. So I have my two if statements for the "restart now" and "cancel" set but now I need an if statement to have it count down from thirty minutes before it executes my restart command. Also if anyone knows how to add a visual timer on there showing how much time is left that would be a plus. Thanks guys!!!

@Echo off

:START

set /p answer=PC WILL RESTART IN 30 MINUTES, PRESS N TO RESTART NOW OR C TO CANCEL

if "%answer%"=="n" (GOTO Label1)
if "%answer%"=="c" (GOTO Label2)
if "TIMER GOES HERE" "==" (GOTO Label1)

:Label1

shutdown -r -t 60 -f

:Label2 

exit

推荐答案

hibernate 类似.

Similar one for hibernate.

@echo off
setlocal enableDelayedExpansion
for /l %%N in (600 -1 1) do (
  set /a "min=%%N/60, sec=%%N%%60, n-=1"
  if !sec! lss 10 set sec=0!sec!
  cls
  choice /c:CN1 /n /m "HIBERNATE in !min!:!sec! - Press N to hibernate Now, or C to Cancel. " /t:1 /d:1
  if not errorlevel 3 goto :break
)
cls
echo HIBERNATE in 0:00 - Press N to hibernate Now, or C to Cancel.
:break
if errorlevel 2 (%windir%System32
undll32.exe powrprof.dll,SetSuspendState Hibernate) else echo Hibernate Canceled
