How can I get a list of Git branches, ordered by most recent commit? – Dev

The best answers to the question “How can I get a list of Git branches, ordered by most recent commit?” in the category Dev.

QUESTION:

I want to get a list of all the branches in a Git repository with the “freshest” branches at the top, where the “freshest” branch is the one that’s been committed to most recently (and is, therefore, more likely to be one I want to pay attention to).

Is there a way I can use Git to either (a) sort the list of branches by latest commit, or (b) get a list of branches together with each one’s last-commit date, in some kind of machine-readable format?

Worst case, I could always run git branch to get a list of all the branches, parse its output, and then git log -n 1 branchname --format=format:%ci for each one, to get each branch’s commit date. But this will run on a Windows box, where spinning up a new process is relatively expensive, so launching the Git executable once per branch could get slow if there are a lot of branches. Is there a way to do all this with a single command?

ANSWER:

List of Git branch names, ordered by most recent commit…

Expanding on Jakub’s answer and Joe’s tip, the following will strip out the “refs/heads/” so the output only displays the branch names:


Command:

git for-each-ref --count=30 --sort=-committerdate refs/heads/ --format="%(refname:short)"

Result:

Recent Git branches

ANSWER:

Use the --sort=-committerdate option of git for-each-ref;

Also available since Git 2.7.0 for git branch:

Basic Usage:

git for-each-ref --sort=-committerdate refs/heads/

# Or using git branch (since version 2.7.0)
git branch --sort=-committerdate  # DESC
git branch --sort=committerdate  # ASC

Result:

Result

Advanced Usage:

git for-each-ref --sort=committerdate refs/heads/ --format="%(HEAD) %(color:yellow)%(refname:short)%(color:reset) - %(color:red)%(objectname:short)%(color:reset) - %(contents:subject) - %(authorname) (%(color:green)%(committerdate:relative)%(color:reset))"

Result:

Result

Pro Usage (Unix):

You can put the following snippet in your ~/.gitconfig. The recentb alias accepts two arguments:

  • refbranch: which branch the ahead and behind columns are calculated against. Default master
  • count: how many recent branches to show. Default 20
[alias]
    # ATTENTION: All aliases prefixed with ! run in /bin/sh make sure you use sh syntax, not bash/zsh or whatever
    recentb = "!r() { refbranch=$1 count=$2; git for-each-ref --sort=-committerdate refs/heads --format="%(refname:short)|%(HEAD)%(color:yellow)%(refname:short)|%(color:bold green)%(committerdate:relative)|%(color:blue)%(subject)|%(color:magenta)%(authorname)%(color:reset)" --color=always --count=${count:-20} | while read line; do branch=$(echo \"$line\" | awk 'BEGIN { FS = \"|\" }; { print $1 }' | tr -d '*'); ahead=$(git rev-list --count \"${refbranch:-origin/master}..${branch}\"); behind=$(git rev-list --count \"${branch}..${refbranch:-origin/master}\"); colorline=$(echo \"$line\" | sed 's/^[^|]*|//'); echo \"$ahead|$behind|$colorline\" | awk -F'|' -vOFS='|' '{$5=substr($5,1,70)}1' ; done | ( echo \"ahead|behind||branch|lastcommit|message|author\\n\" && cat) | column -ts'|';}; r"

Result:

Recentb alias result

ANSWER:

Here’s the optimal code, which combines the other two answers:

git for-each-ref --sort=-committerdate refs/heads/ --format="%(committerdate:short) %(authorname) %(refname:short)"

ANSWER:

Here is a simple command that lists all branches with latest commits:

git branch -v

To order by most recent commit, use

git branch -v --sort=committerdate
