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.

One liner that works with git version 2.34.1 on Linux (bash, zsh), MacOS (bash, zsh), Windows (git bash, powershell inside of Windows Terminal):

git for-each-ref --color --sort=-committerdate --format='%(color: bold magenta)%(align:60,left)%(refname:short)%(color:bold red) %(upstream:track,nobracket)%(end)%(color:nobold yellow)%(align:58,left)%(committerdate:format:%Y-%d-%m %H:%M) (%(committerdate:relative), %(committerdate:format:%A %d))%(end)%(color:green)%(align:24,left)%(authorname)%(end)%(color:green)%(align:64,left)%(contents:lines=1)%(end)' refs/heads/ --count 16

It looks a little different. It shows your current branch too and sorts by most recent commit first:

It also prints gone near branch when upstream branch is unknown/gone. On Windows may output strange characters and random guids, in current shell session type powershell/bash again and all should be fine. If you modify it and wonder why alignment seems smaller than numbers say, try piping to | cat -v and you will see ANSI color escape sequences, they count too.

Adjust --count 16 to print more/less branches.
