使用powershell合并两个文件夹并根据源文件夹重命名文件 [英] Using powershell to merge two folders and rename files based on source folder

问题描述

我有一组这样的文件:

2015_09_22
|____ foo
     |____ common.ext
     |____ common.1.ext
     |____ common.2.ext
     |____ common.3.ext
|____ bar
     |____ common.ext
     |____ common.1.ext
     |____ common.2.ext

我想将它们合并成这样的结构，使用源文件夹名称作为字符串添加到文件名:

I want to merge them into a structure like this, using the source folder name as a string to prepend to the filename:

2015_09_22
|____ foo_common.ext
|____ foo_common.1.ext
|____ foo_common.2.ext
|____ foo_common.3.ext
|____ bar_common.ext
|____ bar_common.1.ext
|____ bar_common.2.ext

{date}\foo 和 {date}\bar 的格式是固定的，但内容可能有不同数量的文件.

The format of {date}\foo and {date}\bar is fixed but the contents could have a variable number of files with those names.

推荐答案

您可以使用以下内容:

cd .\2015_09_22\
Get-ChildItem *\* | ForEach {$_.MoveTo("$($_.Directory.Parent.FullName)\$($_.Directory.Name)_$($_.Name)")}

这会移动文件，但不会删除目录，并且有点难以阅读.所以也许这更合理:

This moves the files, but doesn't remove the directories, and is a little hard to read. So maybe this is more reasonable:

cd .\2015_09_22\

foreach ($dir in (Get-ChildItem -Directory)) {
    foreach ($file in (Get-ChildItem $dir -File)) {
        $dest = "$($file.Directory.Parent.FullName)\$($file.Directory.Name)_$($file.Name)"
        $file.MoveTo($dest)
    }
    $dir.Delete()
}
