I've had essentially that - if a bit fancier to accept an optional argument as well as handle common "mainline" branch names - aliased as `git lint` for a while:

    [alias]
        lint = !git branch --merged ${1-} | grep -v -E -e '^[*]?[ ]*(main|master|[0-9]+[.]([0-9]+|x)-stable)$' -e '^[*][ ]+' | xargs -r -n 1 git branch --delete

so:

    git pull --prune && git lint

sits very high in my history stats

I use this alias:

    prune-local = "!git fetch -p && for branch in $(git branch -vv | awk '/: gone]/{if ($1!=\"\*\") print $1}'); do git branch -d $branch; done"

1. Fetch the latest from my remote, removing any remote tracking branches that no longer exist

2. Enumerate local branches, selecting each that has been marked as no longer having a remote version (ignoring the current branch)

3. Delete the local branch safely

I currently have a TUI addiction. Each time I want something to be easier, I open claude-code and ask for a TUI. Now I have a git worktree manager where I can add/rebase/delete. As TUI library I use Textual which claude handles quite well, especially as it can test-run quite some Python code.

Missed opportunity to call it `git ciao`

The main issue with `git branch --merged` is that if the repo enforces squash merges, it obviously won't work, because SHA of squash-merged commit in main != SHA of the original branch HEAD.

What tools are the best to do the equivalent but for squash-merged branches detections?

Note: this problem is harder than it seems to do safely, because e.g. I can have a branch `foo` locally that was squash-merged on remote, but before it happened, I might have added a few more commits locally and forgot to push. So naively deleting `foo` locally may make me lose data.

I have something similar, but open fzf to select the branches to delete [1].

    function fcleanb -d "fzf git select branches to delete where the upstream has disappeared"
        set -l branches_to_delete (
            git for-each-ref --sort=committerdate --format='%(refname:lstrip=2) %(upstream:track)' refs/heads/ | \
            egrep '\[gone\]$' | grep -v "master" | \
            awk '{print $1}' | $_FZF_BINARY --multi --exit-0 \
        )

        for branch in $branches_to_delete
            git branch -D "$branch"
        end
    end

Speaking of user friendliness of git UI. I am working on a revision control system that (ideally) should be as user friendly as Ctrl+S Ctrl+Z in most common cases. Spent almost a week on design docs, looking for feedback (so far it was very valuable, btw)

https://replicated.wiki/blog/partII.html#navigating-the-hist...

I use

    #!/bin/sh
    
    git checkout main
    git fetch --prune
    git branch | grep -v main | xargs --no-run-if-empty git branch -D
    git pull

Save that next to your git binary, call it whatever you want. It's destructive on purpose.

"ciaclean" is a nice touch.

I assume CIA stands for Clean It All.

I've had this command as 'git drop-merged' for a few years now (put as a script in your path named git-drop-merged:

  #!/bin/sh
  git branch --merged | egrep -v "(^\*|master|main|dev)" | xargs --no-run-if-empty
  git branch -d

Unfortunately doesn't work if the project you work on squashes everything :(

If you are using Fork.app on Mac as your git client, this now exists (For one month now) there too: https://github.com/fork-dev/Tracker/issues/2200#issuecomment...

So effectively "I just discovered xargs"? Not to disparage OP but there isn't anything particularly novel here.

The git plugin in oh-my-zsh has an alias for this: gbda

It also has one for squash-merged branches: gbds

Very useful I've been using them for years

Why is this even a blog post. Tell the young ones to RTFM.
