我的批处理脚本需要帮助。它运行得很好，但是后来当我想要运行它时，不断重复我之前显示的结果。例如，我上周执行了一个程序，呼叫运行echo“程序在上周开始运行”，当我今天试图通过echo“This is today”运行它。它运行并显示以前的结果“
PS代码现在完美运行.... @echo off

答案 0 :(得分：7)
set minbytesize=6442450944中的数字很大
批处理只能处理32位数字。
但是当您引用数字时，将使用字符串比较函数，因此"9"的大小将大于"6442450944"。
要获得正确的比较，您可以在数字前加零，在您的情况下，您知道第二个数字的长度很简单。
...
set "size=000000000000%size%"
set "size=%size:~-10%"
if "%size%" GEQ "%minbytesize%" (goto EXECUTE)
它仍然是一个字符串比较，但它现在也适用于数字。
顺便说一下。这不是你的主要问题
设置ECHO ON以查看问题发生的位置可能是个好主意。
您使用的是什么时间格式？
如果它在一小时内使用带前缀的零，则会在set /a hh=%hh%+100
答案 1 :(得分：4)
如果您在同一个控制台窗口中同时运行它，则问题可能是未初始化的变量，并且您将看到最后的结果。
要使用VBS检查数字，请尝试将其作为代码的第一部分。
留在最后goto :eof以阻止它通过比较落入以下代码。
检查决赛是否比较，以确保他们正在做你想要的。
