Git: How to delete all local branches except master

Checkout to master branch.

The command to delete all branches except master is:
git branch | grep -v "master" | xargs git branch -D

To use the same command in Windows we have to install some utilities

Or, we can use PowerShell command that do the same thing that above command do:
git branch | %{ $_.Trim() } | ?{ $_ -ne 'master' } | %{ git branch -D $_ }
or
git branch -D @(git branch | select-string -NotMatch "master" | Foreach {$_.Line.Trim()})

thank you so much, just added one more check

git branch | %{$.Trim()} | ?{$ -ne 'master' -and $.Substring(0,1) -ne '*'} | %{git branch -D $}

Ha! Sweet. Super simple and super efficient. Thanks for sharing.

I did noticed on the first powershell one liner, I did noticed that one of the response lines was:

"error: branch '* master' not found."

Hi,

I've just checked it again in PowerShell and everything works. I made a quick check like:
git init
git branch new
git branch new2
git branch new3
git branch new4
git branch | grep -v "master" | xargs git branch -D


Just to confirm, are you sure that you installed Gow utilities, input the command correctly and that you are in master branch?

It's the PS script which gives this error, as the git branch prefixes selected branch with asterisk:

❯ git branch |`
  %{ $_.Trim() } |`
  ?{ $_ -ne 'master' } |`
  %{ git branch -D $_ }

Deleted branch <branch1> (was <commit1>).
error: branch '* master' not found.

Could be addressed e.g. by adding check for * master:

git branch |`
  %{ $_.Trim() } |`
  ?{ $_ -ne 'master' -and $_ -ne '* master' } |`
  %{ git branch -D $_ }
