'How do I determine what branch/tag I have checked out in git?

I clone my source using git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git w/. Then I specify a specific branch/tag by doing git checkout <tag name> or git checkout origin/REL<release number>. Sometimes I forget what branch or tag I'm on.

In SVN I would do a svn info to figure out what branch/tag I'm using (I realize that git has distinct definitions for branch and tag but for my purposes they are the same).

How do I determine what branch/tag I am on?

Solution 1:^[1]

The current branch is marked with a * in the output of git branch. Example:

$ git branch
  branch1
* branch2
  master

How do I determine what branch/tag I am on?

First, since Git 2.22 (Q2 2019), you have git branch --show-current which directly shows you your current checked out branch.

Second, it won't show anything if you are in a checked out worktree (created with git worktree add)

For that, check Git 2.23 (Q3 2019), with its "git branch --list" which learned to show branches that are checked out in other worktrees connected to the same repository prefixed with '+', similar to the way the currently checked out branch is shown with '*' in front.

Example:

See commit 6e93814, commit ab31381, commit 2582083 (29 Apr 2019) by Nickolai Belakovski (``).

branch: add worktree info on verbose output

To display worktree path for refs checked out in a linked worktree

The git branch documentation now states:

The current branch will be highlighted in green and marked with an asterisk.
Any branches checked out in linked worktrees will be highlighted in cyan and marked with a plus sign.

If you use the bash shell, you can use __git_ps1 in your bash prompt to show this, for example:

[me@myhost:~/code/myproject] (master)$ ls

Download git-completion.bash to ~/.git-completion.bash

Then in your ~/.bashrc file, add

source ~/.git-completion.bash

Then set your PS1 value to something including $(__git_ps1 "(%s)"), something like:

PS1="[\u@\h:\w]\$(__git_ps1)\\$ "

Some sed and regex magic:

git reflog | grep "checkout: moving from" | sed -n '1p' | sed -e 's/^[[:alnum:]]\+ HEAD@{[[:digit:]]\+}: checkout: moving from \([^[:space:]]\+\) to \([^[:space:]]\+\)$/\2/'

Solution 5:^[5]

Why not consider using a nice prompt for your shell?
Starship for Bash or Oh My Zsh for Zsh, or several superb ones are out there.

You will keep track of more than git branch info once you adopt one.

Solution 6:^[6]

git branch

using this command tells you at what branch you are by an * marker.
