Remove tracking branches no longer on remote

Question

Is there a simple way to delete all tracking branches whose remote equivalent no longer exists?

Example:

Branches (local and remote)

• master
• origin/master
• origin/bug-fix-a
• origin/bug-fix-b
• origin/bug-fix-c

Locally, I only have a master branch. Now I need to work on bug-fix-a, so I check it out, work on it, and push changes to the remote. Next I do the same with bug-fix-b.

Branches (local and remote)

• master
• bug-fix-a
• bug-fix-b
• origin/master
• origin/bug-fix-a
• origin/bug-fix-b
• origin/bug-fix-c

Now I have local branches master, bug-fix-a, bug-fix-b. The Master branch maintainer will merge my changes into master and delete all branches he has already merged.

So the current state is now:

Branches (local and remote)

• master
• bug-fix-a
• bug-fix-b
• origin/master
• origin/bug-fix-c

Now I would like to call some command to delete branches (in this case bug-fix-a, bug-fix-b), which are no longer represented in the remote repository.

It would be something like the existing command git remote prune origin, but more like git local prune origin.

Answer 1

git remote prune origin prunes tracking branches not on the remote.

git branch --merged lists branches that have been merged into the current branch.

xargs git branch -d deletes branches listed on standard input.

Be careful deleting branches listed by git branch --merged. The list could include master or other branches you'd prefer not to delete.

To give yourself the opportunity to edit the list before deleting branches, you could do the following in one line:

git branch --merged >/tmp/merged-branches && \
  vi /tmp/merged-branches && xargs git branch -d </tmp/merged-branches

Answer 2

After the command

git fetch -p

removes the remote references, when you run

git branch -vv

it will show 'gone' as the remote status. For example,

$ git branch -vv
  master                 b900de9 [origin/master: behind 4] Fixed bug
  release/v3.8           fdd2f4e [origin/release/v3.8: behind 2] Fixed bug
  release/v3.9           0d680d0 [origin/release/v3.9: behind 2] Updated comments
  bug/1234               57379e4 [origin/bug/1234: gone] Fixed bug

So you can write a simple script to remove local branches that have gone remotes:

git fetch -p && for branch in $(git branch -vv | grep ': gone]' | awk '{print $1}'); do git branch -D $branch; done

Note that the above uses the "porcelain" command git branch to get the upstream status.

Another way to obtain this status is to use the "plumbing" command git for-each-ref with the interpolation variable %(upstream:track), which will be [gone] just like above.

This approach is somewhat safer, because there is no risk of accidentally matching on part of the commit message.

git fetch -p && for branch in $(git for-each-ref --format '%(refname) %(upstream:track)' refs/heads | awk '$2 == "[gone]" {sub("refs/heads/", "", $1); print $1}'); do git branch -D $branch; done

Answer 3

Most of these answers do not actually answer the original question. I did a bunch of digging and this was the cleanest solution I found. Here is a slightly more thorough version of that answer:

1. Check out your default branch. Usually git checkout master
2. Run git fetch -p && git branch -vv | awk '/: gone]/{print $1}' | xargs git branch -d

Explanation:

Works by pruning your tracking branches then deleting the local ones that show they are "gone" in git branch -vv.

Notes:

If your language is set to something other than English you will need to change gone to the appropriate word. Branches that are local only will not be touched. Branches that have been deleted on remote but were not merged will show a notification but not be deleted on local. If you want to delete those as well change -d to -D.

Answer 4

I wouldn't normally answer a question that already has 16 answers, but all the other answers are wrong, and the right answer is so simple. The question says, "Is there a simple way to delete all tracking branches whose remote equivalent no longer exists?"

If "simple" means deleting them all in one go, not fragile, not dangerous, and without reliance on tools that not all readers will have, then the right answer is: no.

Some answers are simple, but they don't do what was asked. Others do what was asked, but are not simple: all rely on parsing Git output through text-manipulation commands or scripting languages, which may not be present on every system. On top of that, most of the suggestions use porcelain commands, whose output is not designed to be parsed by script ("porcelain" refers to the commands intended for human operation; scripts should use the lower-level "plumbing" commands).

Further reading:

• why you shouldn't parse git branch output in a script.
• tracking branches and the differences between git remote prune, git prune, git fetch --prune

---

If you want to do this safely, for the use case in the question (garbage-collect tracking branches which have been deleted on the server but still exist as local branches) and with high-level Git commands only, you have to

• git fetch --prune (or git fetch -p, which is an alias, or git prune remote origin which does the same thing without fetching, and is probably not what you want most of the time).
• Note any remote branches that are reported as deleted. Or, to find them later on, git branch -v (any orphaned tracking branch will be marked "[gone]").
• git branch -d [branch_name] on each orphaned tracking branch

(which is what some of the other answers propose).

If you want to script a solution, then for-each-ref is your starting point, as in Mark Longair's answer here and this answer to another question, but I can't see a way to exploit it without writing a shell script loop, or using xargs or something.

---

Background explanation

To understand what's happening, you need to appreciate that, in the situation of tracking branches, you have not one branch, but three. (And recall that "branch" means simply a pointer to a commit.)

Given a tracking branch feature/X, the remote repository (server) will have this branch and call it feature/X. Your local repository has a branch remotes/origin/feature/X which means, "This is what the remote told me its feature/X branch was, last time we talked," and finally, the local repository has a branch feature/X which points to your latest commit, and is configured to "track" remotes/origin/feature/X, meaning that you can pull and push to keep them aligned.

At some point, someone has deleted the feature/X on the remote. From that moment, you are left with your local feature/X (which you probably don't want any more, since work on feature X is presumably finished), and your remotes/origin/feature/X which is certainly useless because its only purpose was to remember the state of the server's branch.

And Git will let you automatically clean up the redundant remotes/origin/feature/X -- that's what git fetch --prune does -- but for some reason, it doesn't let you automatically delete your own feature/X... even though your feature/X still contains the orphaned tracking information, so it has the information to identify former tracking branches that have been fully merged. (After all, it can give you the information that lets you do the operation by hand yourself.)

Answer 5

Windows Solution

For Microsoft Windows Powershell:

git checkout master; git remote update origin --prune; git branch -vv | Select-String -Pattern ": gone]" | % { $_.toString().Trim().Split(" ")[0]} | % {git branch -d $_}

Explaination

git checkout master switches to the master branch

git remote update origin --prune prunes remote branches

git branch -vv gets a verbose output of all branches (git reference)

Select-String -Pattern ": gone]" gets only the records where they have been removed from remote.

% { $_.toString().Trim().Split(" ")[0]} get the branch name

% {git branch -d $_} deletes the branch

Answer 6

I found the answer here: How can I delete all git branches which have been merged?

git branch --merged | grep -v "\*" | xargs -n 1 git branch -d

Make sure we keep master

You can ensure that master, or any other branch for that matter, doesn't get removed by adding another grep after the first one. In that case you would go:

git branch --merged | grep -v "\*" | grep -v "YOUR_BRANCH_TO_KEEP" | xargs -n 1 git branch -d

So if we wanted to keep master, develop and staging for instance, we would go:

git branch --merged | grep -v "\*" | grep -v "master" | grep -v "develop" | grep -v "staging" | xargs -n 1 git branch -d

Make this an alias

Since it's a bit long, you might want to add an alias to your .zshrc or .bashrc. Mine is called gbpurge (for git branches purge):

alias gbpurge='git branch --merged | grep -v "\*" | grep -v "master" | grep -v "develop" | grep -v "staging" | xargs -n 1 git branch -d'

Then reload your .bashrc or .zshrc:

. ~/.bashrc

or

. ~/.zshrc

Answer 7

The pattern matching for "gone" in most of the other solutions was a little scary for me. To be safer, this uses the --format flag to pull out each branch's upstream tracking status.

I needed a Windows-friendly version, so this deletes all branches that are listed as "gone" using Powershell:

git branch --list --format "%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)" | 
    ? { $_ -ne "" } | 
    % { git branch -D $_ }

The first line lists the name of local branches whose upstream branch is "gone". The next line removes blank lines (which are output for branches that aren't "gone"), then the branch name is passed to the command to delete the branch.

Answer 8

Remove all branches that have been merged into master, but don't try to remove master itself:

git checkout master && git pull origin master && git fetch -p && git branch -d $(git branch --merged | grep master -v)

or add an alias:

alias gitcleanlocal="git checkout master && git pull origin master && git fetch -p && git branch -d $(git branch --merged | grep master -v)"

Explanation:

git checkout master checkout master branch

git pull origin master ensure local branch has all remote changes merged

git fetch -p remove references to remote branches that have been deleted

git branch -d $(git branch master --merged | grep master -v) delete all branches that have been merged into master, but don't try to remove master itself

Answer 9

You could do this:

git branch -vv | grep 'origin/.*: gone]' | awk '{print $1}' | xargs git branch -d

P.S.: as pointed out by Sam H.

execute this first:

git remote prune origin

Answer 10

TL;DR:

Remove ALL local branches that are not on remote

git fetch -p && git branch -vv | grep ': gone]' | awk '{print $1}' | xargs git branch -D

Remove ALL local branches that are not on remote AND that are fully merged AND that are not used as said in many answers before.

git fetch -p && git branch --merged | grep -v '*' | grep -v 'master' | xargs git branch -d

Explanation

• git fetch -p will prune all branches no longer existing on remote
• git branch -vv will print local branches and pruned branch will be tagged with gone
• grep ': gone]' selects only branch that are gone
• awk '{print $1}' filter the output to display only the name of the branches
• xargs git branch -D will loop over all lines (branches) and force remove this branch

Why git branch -D and not git branch -d else you will have for branches that are not fully merged.

error: The branch 'xxx' is not fully merged.

Answer 11

Yet another answer, because none of the solutions suit my needs on elegance and cross-platformness:

Command to delete local branches not on remote:

for b in $(git for-each-ref --format='%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)' refs/heads); do git branch -d $b; done

To integrate it with gitconfig so it can be run with git branch-prune:

Bash

git config --global alias.branch-prune '!git fetch -p && for b in $(git for-each-ref --format='\''%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)'\'' refs/heads); do git branch -d $b; done'

PowerShell

git config --global alias.branch-prune '!git fetch -p && for b in $(git for-each-ref --format=''%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)'' refs/heads); do git branch -d $b; done'

(Need help in finding a universal command for PowerShell and bash)

Why this answer is the best?

• Offers a complete solution: adds a git branch-prune command to your git
• Works fine from Windows PowerShell
• The core idea is @jason.rickman's bulletproof method using git for-each-ref
• Parsing and filtering is done with --filter so no external dependencies needed

Explanation:

• Adds a new alias to your ~\.gitconfig. After executing this you can simply do git branch-prune
• Inside this alias:
  • Fetches branches with the --prune flag, which "prunes remote-tracking branches no longer on remote"
  • Uses git for-each-ref and --filter, to get a list of the branches are [gone] (no remote)
  • Loops through this list and deletes the branch safely

Answer 12

git fetch -p

This will prune any branches that no longer exist on the remote.

Answer 13

Yet-another-answer for the pile, drawing heavily from Patrick's answer (which I like because it seems to do away with any ambiguity about where gone] will match in the git branch output) but adding a *nix bent.

In its simplest form:

git branch --list --format \
  "%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)" \
  | xargs git branch -D

I have this wrapped up in a git-gone script on my path:

#!/usr/bin/env bash

action() {
  ${DELETE} && xargs git branch -D || cat
}

get_gone() {
  git branch --list --format \
    "%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)"
}

main() {
  DELETE=false
  while [ $# -gt 0 ] ; do
    case "${1}" in
      (-[dD] | --delete) DELETE=true ;;
    esac
    shift
  done
  get_gone | action
}

main "${@}"

NB - The --format option seems to be fairly new; I needed to upgrade git from 2.10.something to 2.16.3 to get it.

EDIT: tweaked to include suggestion about refname:short from Benjamin W.

NB2 - I've only tested in bash, hence the hashbang, but probably portable to sh.

Answer 14

This will delete all the merged local branched except local master reference and the one currently being used:

git branch --merged | grep -v "*" | grep -v "master" | xargs git branch -d

And this will delete all the branches having already been removed from the remote repository referenced by "origin", but are still locally available in "remotes/origin".

git remote prune origin

Answer 15

Might be useful to some, simple one line to clear all local branches except master and develop

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

Answer 16

I don't think there is a built-in command to do this, but it is safe to do the following:

git checkout master
git branch -d bug-fix-a

When you use -d, git will refuse to delete the branch unless it is completely merged into HEAD or its upstream remote-tracking branch. So, you could always loop over the output of git for-each-ref and try to delete each branch. The problem with that approach is that I suspect that you probably don't want bug-fix-d to be deleted just because origin/bug-fix-d contains its history. Instead, you could create a script something like the following:

#!/bin/sh

git checkout master &&
for r in $(git for-each-ref refs/heads --format='%(refname:short)')
do
  if [ x$(git merge-base master "$r") = x$(git rev-parse --verify "$r") ]
  then
    if [ "$r" != "master" ]
    then
      git branch -d "$r"
    fi
  fi
done

Warning: I haven't tested this script - use only with care...

Answer 17

grep gone <(git branch -v) | cut -d ' ' -f 3 | xargs git branch -d

The above command can be used to fetch branches which are merged and deleted in remote and it deletes the local branch which no longer available in remote

Answer 18

Powershell-based solution that I find more legible than many of the implementations here.

# prune deleted remoted branches
git fetch -p

# get all branches and their corresponding remote status
# deleted remotes will be marked [gone]
git branch -v |
  #find ones marked [gone], capture branchName
  select-string -Pattern '^  (?<branchName>\S+)\s+\w+ \[gone\]' | 
  foreach-object{ 
     #delete the captured branchname.
     git branch -D $_.Matches[0].Groups['branchName']
  }

Answer 19

None of this was really right for me. I wanted something that would purge all local branches that were tracking a remote branch, on origin, where the remote branch has been deleted (gone). I did not want to delete local branches that were never set up to track a remote branch (i.e.: my local dev branches). Also I wanted a simple one-liner that just uses git, or other simple CLI tools, rather than writing custom scripts. I ended up using a bit of grep and awk to make this simple command.

This is ultimately what ended up in my ~/.gitconfig:

[alias]
  prune-branches = !git remote prune origin && git branch -vv | grep ': gone]' | awk '{print $1}' | xargs -r git branch -D

Here is a git config --global ... command for easily adding this as git prune-branches:

git config --global alias.prune-branches '!git remote prune origin && git branch -vv | grep '"'"': gone]'"'"' | awk '"'"'{print $1}'"'"' | xargs -r git branch -d'

NOTE: In the config command, I use the -d option to git branch rather than -D, as I do in my actual config. I use -D because I don't want to hear Git complain about unmerged branches. You may want this functionality as well. If so, simply use -D instead of -d at the end of that config command.

Answer 20

Based on info above, this worked for me:

git br -d `git br -vv | grep ': gone] ' | awk '{print $1}' | xargs`

It removes all local branches with are ': gone] ' on remote.

Answer 21

Based on Git Tip: Deleting Old Local Branches, which looks similar to jason.rickman's solution I implemented a custom command for this purpose called git gone using Bash:

$ git gone
usage: git gone [-pndD] [<branch>=origin]
OPTIONS
  -p  prune remote branch
  -n  dry run: list the gone branches
  -d  delete the gone branches
  -D  delete the gone branches forcefully

EXAMPLES
git gone -pn    prune and dry run
git gone -d     delete the gone branches

git gone -pn combines the pruning and listing the "gone" branches:

$ git gone -pn
  bport/fix-server-broadcast         b472d5d2b [origin/bport/fix-server-broadcast: gone] Bump modules
  fport/rangepos                     45c857d15 [origin/fport/rangepos: gone] Bump modules

Then you can pull the trigger using git gone -d or git gone -D.

Notes

• The regular expression I used is "$BRANCH/.*: gone]" where $BRANCH would normally be origin. This probably won't work if your Git output is localized to French etc.
• Sebastian Wiesner also ported it to Rust for Windows users. That one is also called git gone.

Answer 22

Drawing heavily from a number of other answers here, I've ended up with the following (git 2.13 and above only, I believe), which should work on any UNIX-like shell:

git for-each-ref --shell --format='ref=%(if:equals=[gone])%(upstream:track)%(then)%(refname)%(end)' refs/heads | while read entry; do eval "$entry"; [ ! -z "$ref" ] && git update-ref -d "$ref" && echo "deleted $ref"; done

This notably uses for-each-ref instead of branch (as branch is a "porcelain" command designed for human-readable output, not machine-processing) and uses its --shell argument to get properly escaped output (this allows us to not worry about any character in the ref name).

Answer 23

A simpler solution for Windows or others who don't want to/can't script the command line or who don't want to bother with PowerShell.

Dump the branch list into a file git branch > branches.txt
(or git branch --merged > branches.txt, if you're the belt and suspenders type; git branch -d will protect against deleting unmerged branches)

Open that file in your editor and combine all the lines (I used sublime text, so highlight all and press ctrl+j)

Add git branch -d ahead of your branch list.

Select all, copy, and paste (right click in windows cmd window) into the command line.

Answer 24

I like using pipes because it makes the command easier to read.

This is my solution if you would like to remove all branches except master.

git branch | grep -v master | xargs -n 1 git branch -D

To delete other branches that match your criteria, modify the first and second block.

git branch --merged | grep feature_name | xargs -n 1 git branch -D

Answer 25

May be this command is what you want.

After run:

git remote prune origin

then run:

diff <(git branch | sed -e 's/*/ /g') <(git branch -r | sed -e 's/origin\///g') | grep '^<'

this will show all branch which not in (git branch -r) but in (git branch)

This method have a problem, it will also show the branch in local which have not pushed before

Answer 26

The real challenge is when the maintainer squashes the commits. Then, the solutions using git built-in functionality such as --merged does not help.

The tool git-delete-merged-branches allows for a convenient deletion of branches. I especially like the interactive mode.

Installation (requires python3):

pip install git-delete-merged-branches

Then execute

git-delete-merged-branches --effort=3

--effort=3 is important to enable deletion of squashed branches.

Alternatives

• @teppeis/git-delete-squashed: With node.js installed execute npx @teppeis/git-delete-squashed. Supports main branch.
• git-delete-squashed: Not maintained: Misses functionality for main branch. @teppeis/git-delete-squashed is based on this.

Answer 27

While the above answers cover how to prune branches manually, this answer adds automation to solve this. git now has a new setting to prune stale branches that are no longer on the remote for every fetch action. This is great because we no longer have to manually call remote prune every time we delete branches (git pull also calls git fetch).

Enable prune behaviour for every fetch

To enable this in the global config:

git config --global fetch.prune true

Making the thing happen automatically means you can forget to add this setting on new machines. It just works.

Enable prune behaviour for every fetch on specific remotes

git config --global remote.<name>.prune true

Local automated pruning

We can apply the same command for local pruning as well without the --global flag.

.gitconfig

The commands above apply to the global and local .gitconfig as follows:

...
[fetch]
    prune = true

I can recommend adding this to an ansible configuration or to your dotfiles repository (.gitconfig) to automate the setup for the future.

The configuration setting calls the below command on every fetch:

git remote prune <remote name>

Summary

To prune references as part of your normal workflow without needing to remember to run that, set fetch.prune globally or remote.<name>.prune per-remote in the config. See git-config.

Answer 28

I came up with this bash script. It always keep the branches develop, qa, master.

git-clear() {
  git pull -a > /dev/null

  local branches=$(git branch --merged | grep -v 'develop' | grep -v 'master' | grep -v 'qa' | sed 's/^\s*//')
  branches=(${branches//;/ })

  if [ -z $branches ]; then
    echo 'No branches to delete...'
    return;
  fi

  echo $branches

  echo 'Do you want to delete these merged branches? (y/n)'
  read yn
  case $yn in
      [^Yy]* ) return;;
  esac

  echo 'Deleting...'

  git remote prune origin
  echo $branches | xargs git branch -d
  git branch -vv
}

Answer 29

I use a short method to do the trick, I recommend you to do the same as it could save some hours & give you more visibility

Just add the following snippet into your .bashrc (.bashprofile on macos).

git-cleaner() { git fetch --all --prune && git branch --merged | grep -v -E "\bmaster|preprod|dmz\b" | xargs -n 1 git branch -d ;};

1. Fetch all remotes
2. Get only merged branches from git
3. Remove from this list the "protected / important" branches
4. Remove the rest (e.g, clean and merged branches)

You'll have to edit the grep regex in order to fit to your needs (here, it prevent master, preprod and dmz from deletion)

Answer 30

This worked for me:

git branch -r | awk '{print $1}' | egrep -v -f /dev/fd/0 <(git branch -vv | grep origin) | awk '{print $1}' | xargs git branch -d
