Rename file by replacing character and overwrite

Question

On Windows XP, in a folder of files, I need to rename some files, replacing one character in the filename with another and overwriting any files that already have that name.

Answer 1

First, you need to filter to get the files that you actually want to rename.

Get-ChildItem . -include *.xml | Where-Object { $_.name -match "A$" }

And feed this to Move-Item to rename:

Get-ChildItem . -include *.xml | Where-Object { $_.name -match "A$" } | Move-Item -destination { $_.name -replace "A$", "b" }
