1/14/2024 0 Comments Git delete branch matching patternIf you're new to using pull requests and just want to see what steps you should follow, here's my git pull request checklist which you may find helpful. Delete the 'test' branch even if the 'master' branch (or whichever branch is currently checked out) does not have all commits from the test branch. The next fetch or pull will create them again unless you configure them not to. What if you want to keep the branch around so you can always go back and see when it was merged? We'll get to that at the end of this post. Delete the remote-tracking branches 'todo', 'html' and 'man'. You can create another branch, and even give it the same name, but don't recycle branches you've already associated with a pull request for use with any other work. You can use either xargs ( -n 1) or, as in your own code here, sh, to invoke git update-ref. Unfortunately bulk delete is still going to be slow: git update-ref -d only works on one at a time. If you wind up deleting a branch you didnt intend to, you can easily recover it with the info provided by Git during the delete. Reusing the patch-1 branch (after its original PR has been merged and closed) is a good way to cause problems in your git repository. Start with git for-each-ref rather than git show-ref that will get you the set of refs in a single command. At this point, the pull request is complete, and future commits should only be made on master, not patch-1. When a local branch is started off a remote-tracking branch, Git sets up the branch (specifically the branch..remote and branch..merge configuration entries) so that git pull will appropriately merge from the remote-tracking branch.After the merge (assuming a new merge commit is added), both master and patch-1 point to a new merge commit. Branches in Git are simply pointers (references) to the SHA-1 value of the head commit, which is why the condition uses References. Before the merge, master and patch-1 both point to separate commits in git's commit history. Consider a scenario in which a branch patch-1 is about to be merged with the master branch through a pull request. Back to the previous example, if you want to delete the remote Git tag named v1.0, you would run. To delete a remote Git tag, use the git push command with the delete option and specify the tag name. They don't add any significant technical overhead, but they make it more difficult for humans to work with lists of branches in the repository.Ä«ranches can be safely removed without risk of losing any changes. Second, delete the tag from the remote repository. In most cases, branches, especially branches that were related to a pull request that has since been accepted, serve no purpose. Why should you delete old branches from your git repositories? There are two main reasons: This is a safe operation in that Git prevents you from deleting the branch if it has. This is synonymous with git branch -list. Thatâs a script for another day.It's a common housekeeping practice to delete git branches once they're no longer used, but this practice isn't necessarily universal, or universally understood. List all of the branches in your repository. This does not clean up any local branches that were never pushed to the remote server. You should always run step 0 and step 3 to validate the branches you are going to be deleting before running step 4. This filters our list down to only lines that match the regex origin/.*: gone] leaving us with Next, we pipe the output from git branch -vv into grep âorigin/.*: gone]â. #⦠2) Filter git branches down to only those with deleted upstream/remote counterparts Git branch -vv will list all local branches along with some additional information such as their related upstream/remote branch and latest commit messageįeature/some-local-only-feature cba8191 Some commit messageįeature/some-old-feature cba2191 Some commit message about some old featureįeature/some-active-feature wba2191 Some active feature branch These stale branches have already been removed from the remote repository referenced by , but are still locally available in âremotes/â. 0) Prune Remote BranchesÄeletes all stale remote-tracking branches under . Update: I have a script that can do all of this here GitDeleteOldLocalBranches.ps1. I am shamelessly stealing the format of the original post as I liked the way he laid it out. My first instinct in all of these cases is to translate it into PowerShell. So I was reading Git Tip: Deleting Old Local Branches, but the code was for Bash/Linux.
