Powershell: Delete all local branches except master

use carefully December 10, 2020

Assuming your local git repo is on master, you can delete all local branches except master using this one-line powershell script:

git branch | foreach { $_.split( "`n" ) } | foreach { if ($_ -ne '* master' ) { git branch -D $_.replace(' ', '') } }

I strongly recommend doing first a dry-run to see which branches will be deleted:

git branch | foreach { $_.split( "`n" ) } | foreach { if ($_ -ne '* master' ) { write $_ } }
