Can I delete all the local branches except the current one?

问题

I want to delete all branches that get listed in the output of ...

$ git branch

... but keeping current branch, in one step. Is that possible? If so, how?

回答1:

Based on @pankijs answer, I made two git aliases:

[alias]
    # Delete all local branches but master and the current one, only if they are fully merged with master.
    br-delete-useless = "!f(){\
        git branch | grep -v "master" | grep -v ^* | xargs git branch -d;\
    }; f"
    # Delete all local branches but master and the current one.
    br-delete-useless-force = "!f(){\
        git branch | grep -v "master" | grep -v ^* | xargs git branch -D;\
    }; f"

To be added in ~/.gitconfig

And, as @torek pointed out:

Note that lowercase -d won't delete a "non fully merged" branch (see the documentation). Using -D will delete such branches, even if this causes commits to become "lost"; use this with great care, as this deletes the branch reflogs as well, so that the usual "recover from accidental deletion" stuff does not work either.

Basically, never use the -force version if you're not 300% sure you won't lose anything important. Because it's lost forever.

回答2:

$ git branch | grep -v "master" | xargs git branch -D

will delete all branches except master (replace master with branch you want to keep, but then it will delete master)

回答3:

git branch -d (or -D) allows multiple branch names, but it's a bit tricky to automatically supply "all local branches excluding the one I'm on now" without writing at least a little bit of code.

The "best" (formally correct) method is to use git for-each-ref to get the branch names:

git for-each-ref --format '%(refname:short)' refs/heads

but then it's even harder to figure out which branch you're on (git symbolic-ref HEAD is the "formally correct" method for this, if you want to write a fancy script).

More conveniently, you can use git branch, which prints your local branch names preceded by two spaces or (for the current branch) by an asterisk *. So, run this through something to remove the * version and you're left with space-separated branch names, which you can then pass to git branch -d:

git branch -d $(git branch | grep -v '^*')

or:

git branch | grep -v '^*' | xargs git branch -d

Note that lowercase -d won't delete a "non fully merged" branch (see the documentation). Using -D will delete such branches, even if this causes commits to become "lost"; use this with great care, as this deletes the branch reflogs as well, so that the usual "recover from accidental deletion" stuff does not work either.

To remove all merged branches(except current -v ‘*’):

git branch --merged | grep -v '*' | xargs git branch -D

also I made such command for repo complete clean up:

alias git-clean="git branch  | grep -v '*' | grep -v 'master' | xargs git branch -D  && git reset --hard && git clean -d -x -f"

taken from here.

回答5:

Delete all branches except a specific branch:

git branch | grep -v "branch name" | xargs git branch -D

Delete all local branches except develop and master

git branch | grep -v "develop" | grep -v "master" | xargs git branch -D

回答6:

For Windows, in Powershell use:

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

回答7:

Delete all merged branch locally:

git branch -D `git branch --merged | grep -v \* | xargs`

Delete all branches except a specific branch:

git branch | grep -v "branch name" | xargs git branch -D

Delete all local branches except develop and master

git branch | grep -v "develop" | grep -v "master" | xargs git branch -D

回答8:

I once created this construct for my Windows environment. Maybe it'll help someone else. During execution, the master and current branch are not deleted. All other merged branches will be deleted regardless.

@echo off
cd PATH_TO_YOUR_REPO

REM -- Variable declerations
set "textFile=tempBranchInfo.txt"
set "branchToKeep=master"
set "branchToReplaceWith="
git branch --merged > %textFile%

REM -- remove "master" from list to keep the branch
for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
    set "line=%%i"
    setlocal enabledelayedexpansion
    >>"%textFile%" echo(!line:%branchToKeep%=%branchToReplaceWith%!
    endlocal
)

REM -- execute branch delete commands
for /f "delims=" %%a in (%textFile%) do (
    git branch -D %%a
)

REM -- remove temp-file with branch information inside
DEL %textFile%

REM -- show local branches after the cleaning
echo Local branches:
git branch

pause 
exit

回答9:

Assuming git branch shows the current branch prefixed with *; Using Powershell the following one liner will delete all branches that don't start with *.

git branch | ? { $_ -lt "*" } | % { git branch -D $_.Trim() }

? = Where-Object

% = Foreach-Object

回答10:

first (switch to the branch you want to keep > ex: master):

git checkout master

second (make sure you are on master)

git branch -D $(git branch)

回答11:

IMHO, the safest way of removing local branches is:

git branch -av | grep "\[gone\]" | awk '{print $1}' | xargs git branch -d

回答12:

So I see a lot of hard coded branch names here... And I think my answer here is more accurate to the "current branch" part of the question whilst keeping it single line and readable to bash newbies like me. Just to place credit where it's due, the answer is rather obviously also based on @pankijs's answer.

git branch | grep -v $(git branch --show-current) | xargs git branch -d

and I have it aliased on one line in my .bash_aliases in debian aswell.

alias gitbclean='git branch | grep -v $(git branch --show-current) | xargs git branch -d'

(Though I thinks some bash features need to be enabled for the sub command to run on some command lines)
