Capitalize the first letter of each word in a filename with powershell

Question

I want to change the names of some files automatically.

With this code I change the lowercase letters to uppercase:

get-childitem *.mp3 | foreach { if ($.Name -cne $.Name.ToUpper()) { ren $.FullName $.Name.ToUpper() } }

But I only want the first letter of each word to be uppercase.

Answer 1

You can use ToTitleCase Method:

$TextInfo = (Get-Culture).TextInfo
$TextInfo.ToTitleCase("one two three")

outputs

One Two Three

$TextInfo = (Get-Culture).TextInfo
get-childitem *.mp3 | foreach { $NewName = $TextInfo.ToTitleCase($_); ren $_.FullName $NewName }
