我有一个相当有趣的delima。我正在尝试在目录中找到最新的7个文件。如果我只是从命令提示符运行dir /o-d /a-d /b|find /n /v ""，它会返回顶部的最新7个文件，但如果我在批处理文件中的for循环中运行它，则不会。他们出了故障。我正在使用的代码是：
@echo off
setlocal
cd /d %~dp0
for /f "tokens=*" %%a in ('dir /o-n /b /a-d^|find /n /v ""' ) do (
echo %%a
)
我打算使用带有for /l循环的数字来获取最新的7个文件但我不知道为什么会发生这种情况。以下是显示差异的文件。
