[文件操作] [已解决]批处理如何检测第二层子目录文件是否存在？

@echo off
set "OutFile=%userprofile%\Desktop\结果.txt"
>"%OutFile%" type nul
for /f "delims=" %%a in ('dir /b /ad') do (
    echo 一级文件夹：%%a
    pushd "%%a"
    for /f "delims=" %%b in ('dir /b /ad') do (
        if exist "%%b\*.pdf" (
            >>"%OutFile%" echo "%%a\%%b：有pdf文件"
        )
    )
    popd
)
复制代码

function dl($path){[regex]::Matches(($path),'\\').count}
$currentlayer=(dl (gl))+2 #这里是层级,2代表第二层
(dir -Recurse|%{
    $sourcelayer=(dl $_.DirectoryName)
    if($currentlayer -eq $sourcelayer){$_.FullName}
})|sc $env:USERPROFILE\Desktop\记录.txt
