One-liner with similar functionality:

git for-each-ref --color --sort=-committerdate --format=$'%(color:red)%(ahead-behind:HEAD)\t%(color:blue)%(refname:short)\t%(color:yellow)%(committerdate:relative)\t%(color:default)%(describe)' refs/heads/ --no-merged | \
    sed 's/ /\t/' | \
    column --separator=$'\t' --table --table-columns='Ahead,Behind,Branch Name,Last Commit,Description'

for macos:

bb = !git for-each-ref --color --sort=-committerdate --format=$'%(color:red)%(ahead-behind:HEAD)\t%(color:blue)%(refname:short)\t%(color:yellow)%(committerdate:relative)\t%(color:default)%(describe)' refs/heads/ --no-merged | sed 's/ /\t/' | column -s=$'\t' -t -c 'Ahead,Behind,Branch Name,Last Commit,Description'

column in macos is BSD (not GNU) and has different argument names.

Thanks for the amazing script !

One change for anyone not wanting two fatal errors and some more output, when you run it by mistake from a directory which is not git repo:

diff --git a/git-better-branch.sh b/git-better-branch.sh

I might be a bit too late, but none of the above is working out for me. Is it depecrated? or am I dumb
I'm using macos, the solution proposed by @evilr00t for macos doesn't show any output.
the .sh file gives an empty table with no branches. I did git branch -a to make sure I'm in the correct path.
Is there any suggestions?

@Azzam-Alotaibi Hey, i found out that cloning a repository only checkouts the default branch. This script only shows the branches you have checked out. And this script does not show the default branch.

It uses git for-each-ref command to get all the branches and selects the branches that starts with refs/heads

To checkout all the remote branches at once, run this in bash:

for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master `; do
   git branch --track ${branch#remotes/origin/} $branch
done

I realized this script only uses local branches so if your branches change remotely this may not show accurate information. I need to test if this is the case.
