File with no extension not changing on powershell

Question

I have the following code:

Get-ChildItem . *. | Rename-Item -NewName {$_.Name -replace 'line21','line21.map52'}

producing this error:

file: line21 is currently of type File (No extension).

When trying to change it to another extension it does not change.

However for the same scenario, it works perfectly fine if I took another file:

Get-ChildItem . *. | Rename-Item -NewName {$_.Name -replace 'line22.txt','line22.map52'}

Answer 1

This behavior is happening, because your Get-ChildItem command is only retrieving files/folders whose names match *.. The file name "line21" does not match *. so it is being excluded.

Change your command to this:

Get-ChildItem -Path . -Include * | Rename-Item -NewName {$_.Name -replace 'line21','line21.map52'};
