Change multiple folder name from %-% to % (delete everything after the hyphen)

Question

I have a folder containing multiple sub folders named like : 12345 - textfoldername

I want to rename all these sub folders by keeping just the first number (12345) and delete all the rest ( - textfoldername).

How can I build the windows script for that.

Thanks for your help !

Are you sure you want to use `bash` on windows? Did you mean `batch` (as in Windows `cmd`) instead? — Socowi, Jun 06 '20 at 10:40

With powershell, use Get-ChildItem to discover all the subfolders, then use Rename-Item to rename:

Get-ChildItem path\to\root\directory -Directory |Rename-Item -NewName {$_.Name -replace ' - .+$'}

The -replace operator with remove - and anything thereafter in the existing name (or, if - something isn't found, ignore it)
