Thanks!

Guys, I understand the commands that how can I list all remote/local branches along with when was it last commited, who made the last commit, last commit id, last commit message etc, sorted by committerdate .... but is there any way that I can list all branches that has their last commits within a date range ... just like we have --since and --until for git log ... for example, I want to list all branches that were being last commited before 6 months ago, or say, all branches that were last commited before "Jan 01 2021"

but is there any way that I can list all branches that has their last commits within a date range ... just like we have --since and --until for git log ... for example, I want to list all branches that were being last commited before 6 months ago, or say, all branches that were last commited before "Jan 01 2021"

I would like the same if possible. But, thanks for the current version as well!

Yes, it's possible. Here's some information on comparing dates in Bash scripts, you'd want to extract the dates from the git output line-by-line, convert them from text to a comparable date format, and compare against your target date to know whether to display them or not:

See comment above.

Thanks for this

thx man 👍

Another way to do this via gitconfig aliases:

rsanheim/dotfiles#34

You can use the command below if you want to filter the branches that were updated X - days ago.

git branch -r --format="%(committerdate:iso8601), %(committerdate:relative) - %(refname:short)" | grep -v [H]EAD | awk -v dateA="$(date -d "$(date +%Y-%m-%d) - 3 days" +%Y-%m-%d)" -F '|' 'dateA<=$1" "$2' | awk -F '/' '{ print $NF }'

From the above command replace the 3 days with your X no of days

Here's my version of this.

for branch in `git branch -r | grep -v HEAD`;
	do printf "%-40s\\t%20s\\n" $branch "`git show --format="%ci %cr" $branch | head -n 1`"; 
done | sort -k 2

Here's a version sorting by committer date, including colour formatting, that is easy to add as a git alias:

❯ git branch -a --sort=-creatordate --format='%(color:red)%(committerdate:iso8601)%(color:reset) %(align:8)(%(ahead-behind:HEAD))%(end) %(color:blue)%(align:40)%(refname:short)%(end)%(color:reset) %(color:white)%(contents:subject) %(color:yellow)(%(committerdate:relative))%(color:reset)'

Example output:

Git aliases:

[alias]
        br = "branch --format='%(color:red)%(committerdate:iso8601)%(color:reset) %(align:8)(%(ahead-behind:HEAD))%(end) %(color:blue)%(align:40)%(refname:short)%(end)%(color:reset) %(color:white)%(contents:subject) %(color:yellow)(%(committerdate:relative))%(color:reset)' --sort=-creatordate"
        newestb = "br --sort=-committerdate"
        oldestb = "br --sort=committerdate"

It can then be composed with other flags like -r, -a, --merged=main, etc.

@bjeanes this looks really nice but I get this error:

fatal: unknown field name: ahead-behind:HEAD

That’s interesting. What git version? I can’t think of a reason that HEAD wouldn’t be defined, but you could change it to ‘main’ or some other ref

Great thread, thank you!

@bjeanes was on 2.39.0, upgrading to the latest version of git solved the issue. Thank you!
