Powershell: replace special characters of file names

Question

I should start off by saying that I am still a beginner in powershell scripting.

I am trying to rename all files recursively in a directory by replacing a "+" with a " " in the file name.

The command I use is: Get-ChildItem -File -Recurse | Rename-Item -NewName {$_.name -replace "+", " "} but doesn't work and gives me the following error:

Instead if I do this: Get-ChildItem -File -Recurse | Rename-Item -NewName {$_.name -replace "a", " "} everything works well.

I think the problem is with the "+" character but can't find anything on the web that tackles this problem. Does anyone know how to represent it or how to solve this?

Answer 1

You must escape the plus sign and the command should work:

Get-ChildItem -File -Recurse | Rename-Item -NewName {$_.name -replace "\+", " "}
