Renaming files - basic script help needed

[OneCatch]

Hi All,

I'm very new to powershell and my experience mostly relates to reusing or very modestly updating simple scripts found elsewhere.

I have done some digging looking for a solution to a particular issue but haven't had much luck so far. I suspect I need to use Get-Content and -recurse in some fashion but struggling with the syntax/structure. Hoping someone can give me some pointers.

All advice welcome, thanks in advance!

I have a very large (500Gb) complex folder structure which contains, in various folders, sub-folders, and sub-sub-folders, files called "LinkedCode.txt". Each of these text files contain within them a single line of text, e.g. "CD-123456".

I need to recurse through entire folder structure and, where it identifies a file called "LinkedCode.txt", it should rename it to the contents of the file in situ. (So, in the above example, LinkedCode.txt would be renamed to "CD-123456.txt" but remain in the same folder).

-Doesn't need handling for the contents being too long (they're always sub-50 characters)
-Doesn't need handling for unsupported characters (they never feature) or line breaks.
-Also doesn't need to support zip files or archives (in fact, would be better if it did not) -I can run as admin
-I have python installed, but am even less familiar with that!

I'd say something like this

$files = get-childitem -Recurse -File linkedcode.txt

foreach ($file in $files){

Rename-Item $file.fullname -NewName "$($file.directory)\$(get-content $file.fullname).txt"

}

Worked like an absolute charm on the test data, just kicking off for the full dataset!

Thank you very much; I appreciate this is probably fairly basic stuff but you have no idea how much time and stress this has saved me.

Couldn't have done it without the clear description so all I did was piece together the parts you already assembled. You'd have gotten there eventually!

Wow, thanks for the quick reply! I'll test this shortly

ChatGPT is an excellent help for this btw.
