Powershell 更改文件夹内一个子文件夹（副文件夹名称）中的部分文件名

Question

I'd like to bulk rename files filtered by folder name.

I have used the following code

dir .\* -include "*Plantegninger*"-recurse| Rename-Item -NewName {$_.name -replace "-00K-","-00U-"}

In the above code the files I want to replace, part of name, are in subfolder named "Plantegninger" I want to change -00K- to -00U- I have many sub folders with this name within sub folders in my main folder. Therefore I'm trying to do this recursively. But I believe this is filtering by filename and not sub folder name. How do I filter by sub folder name, then change file name only within sub folders of that particular name? Also can I filter by sub folder name and then by filename within that sub folder?

If you split the operation into two distinct steps it becomes easier to reason about:

1. Enumerate all subfolders with the given name
2. Rename relevant files in each subfolder

# enumerate relevant sub folders
$subfolders = Get-ChildItem -Filter '*Plantegninger*' -Directory -Recurse

# rename files in subfolders 
$subfolders |Get-ChildItem -File |Rename-Item -NewName {$_.Name -replace "-00K-","-00U-"}

Once you have it working as intended, you can always combine the statements to a single pipeline again (if desired - I personally find it more readable with separate statements):

Get-ChildItem -Filter '*Plantegninger*' -Directory -Recurse |Get-ChildItem -File |Rename-Item -NewName {$_.Name -replace "-00K-","-00U-"}
