我正在编写一个小程序来在特定时间关闭计算机。虽然有些不对劲

Question

我的代码如下。它应该是一个简单的代码来检查时间，并将它与我希望 child 的计算机在晚上关闭的两个不同时间进行比较。我对编码有非常基本的理解，因为我没有真正对非常极端的编码做过任何事情。我想我会试一试，但我不完全确定我在代码中做错了什么，我能够完成不同的步骤，直到我到达 if 语句所在的位置：if %yesno% EQU y (。 ...以及此后的任何事情，它说，出于某种原因，此时不期望 if 语句，然后立即关闭 window。我能够非常快速地截屏。我的所有代码都基于对代码不同部分的多次 google 搜索。如果有人能帮忙，那将是非常有用的。

Answer 1

如果 mytime 高于 start，则 if %mytime% GEQ ~start 下的所有内容仅应运行，因此该行下的所有内容都应放在括号中。此外，如果您的 if 语句有一个 else，第一个右括号 else 和最后一个左括号需要在同一行上。

@echo off

set start=11
set end=19

set mytime=%time:~0,2%

:Start
if %mytime% GEQ %start% (
    if %mytime% LEQ %end% (
        shutdown -s -f -t 60 -c "Your computer is about to be shut down in 1 minute"
    ) else (  
        echo This program is Operating correctly
        sleep 1800
        goto :Start
    )
)
