Windows 脚本 for 循环

Question

我是 Windows 脚本的新手。我写了一个小批处理文件来移动大目录中的子目录和文件。

@ECHO OFF
for /f %x in ('dir /ad /b') do move %xipad %x\
for /f %x in ('dir /ad /b') do md %x\thumbs
for /f %x in ('dir /ad /b') do move %x\*thumb.png %x\thumbs\
for /f %x in ('dir /ad /b') do move %x\*thumb.jpg %x\thumbs\
for /f %x in ('dir /ad /b') do del %x\%xipad\*thumb.png
for /f %x in ('dir /ad /b') do del %x\%xipad\*thumb.jpg
for /f %x in ('dir /ad /b') do del %x\xml.php
for /f %x in ('dir /ad /b') do del %x\%xipad\xml.php

看起来我可以将所有命令放入一个“for/f %x in...”循环中，然后在其中执行逻辑。我可能应该检查扩展名是 .png 还是 .jpg(而不是使用两个单独的命令)。执行这两个操作的最佳方法是什么？此外，我还应该实现其他措施来改善这一点吗？

PowerShell 在此实例中看起来有点冗长，但这里还是一个示例。同样，正如我在评论中提到的那样 - 如果您现在正在尝试学习一种适用于 Windows 的脚本语言，请帮自己一个忙，学习 PowerShell!

#Get the directories we're going to work with:
Get-ChildItem -Path d:\rootdirectory\ | ? {$_.PSIsContainer} | % {
    #Remove all xml.php files from current directory and current directory ipad.
    Remove-Item ($_.FullName + "\xml.php")
    #For all the files in the directory move the each "ipad" directory into the directory with the same name.
    If ($_.Name -like *ipad) {  
        #Delete all  png and jpg images with "thumb" in the name from each current directories ipad directory
        Get-ChildItem $_ -filter "*thumb* | ? {($_.Extension -eq "jpg") -or ($_.Extension -eq "png")} | % {
            Remove-Item $_
        }
        #...Then actually move the item
        Move-Item $_ -Destination $_.FullName.Replace("ipad","")}
    }
    #Use else to work on the remainder of the directories:
    else {
        #Create a directory called "thumbs" inside all of the current directories
        $thumbDir = New-Item -ItemType Directory -Path ($_.FullName + "\thumbs\")
        #Move all png and jpg files in the current directory with "thumb" in the name into the "thumbs" directory.
        Get-ChildItem $_ -filter "*thumb* | ? {($_.Extension -eq "jpg") -or ($_.Extension -eq "png")} | % {
            Move-Item $_ -Destination $thumbDir.FullName
    }
}
