如何使用Powershell递归重命名文件夹? [英] How do I recursively rename folders with Powershell?

问题描述

使用PS进行递归重命名很简单(例如迈克·奥蒙德的博客):

Recursive renaming files using PS is trivial (variation on example from Mike Ormond's blog):

dir *_t*.gif -recurse 
    | foreach { move-item -literal $_ $_.Name.Replace("_thumb[1]", "")}

我正在尝试递归重命名文件夹结构.

I'm trying to recursively rename a folder structure.

用例是我希望能够重命名整个VS.NET解决方案(例如，从Foo.Bar更改为Bar.Foo).为此，需要执行几个步骤:

The use case is I'd like to be able to rename a whole VS.NET Solution (e.g. from Foo.Bar to Bar.Foo). To do this there are several steps:

1. 重命名文件夹(例如\ Foo.Bar \ Foo.Bar.Model => \ Bar.Foo \ Bar.Foo.Model)
2. 重命名文件(例如Foo.Bar.Model.csproj => Bar.Foo.Model.csproj)
3. 在文件内查找和替换以更正名称空间更改(例如'namespace Foo.Bar'=>'namespace Bar.Foo')

我目前正在此过程的第一步.

I'm currently working the first step in this process.

我发现此帖子，其中谈到了挑战，并提出了解决方案，但没有讨论该解决方案是什么.

I found this posting, which talks about the challenges, and claims a solution but doesn't talk about what that solution is.

我一直碰到递归墙.如果我让PS使用标志来处理递归，则父文件夹将在子文件夹之前重命名，并且脚本会引发错误.如果我尝试自己实施递归，那么我的头会很疼，而且事情会变得非常糟糕-在我的生命中，我无法让事物在递归树的尾部开始其重命名.

I keep running into the recursion wall. If I let PS deal with the recursion using a flag, the parent folder gets renamed before the children, and the script throws an error. If I try to implement the recursion myself, my head get's all achy and things go horribly wrong - for the life of me I cannot get things to start their renames at the tail of the recursion tree.

rbellamy最终得到的解决方案是:

Here's the solution rbellamy ended up with:

Get-ChildItem $Path -Recurse | %{$_.FullName} |
Sort-Object -Property Length -Descending |
% {
    Write-Host $_
    $Item = Get-Item $_
    $PathRoot = $Item.FullName | Split-Path
    $OldName = $Item.FullName | Split-Path -Leaf
    $NewName = $OldName -replace $OldText, $NewText
    $NewPath = $PathRoot | Join-Path -ChildPath $NewName
    if (!$Item.PSIsContainer -and $Extension -contains $Item.Extension) {
        (Get-Content $Item) | % {
            #Write-Host $_
            $_ -replace $OldText, $NewText
        } | Set-Content $Item
    }
    if ($OldName.Contains($OldText)) {
        Rename-Item -Path $Item.FullName -NewName $NewPath
    }
}
