Determine the Git Branch You're On

Branching is one of the most used features of git. People usually change branches all the time and need to determine which branch are they on, constantly.

Use Branch Command

The first git subcommand that deals with branches is the branch command. Just by writing this command down, a list of all your local branches and the branch you are on will be shown. Enter:

git branch

And the output will be something like this:

  aerabi/add-readme
  aerabi/add-github-actions
* master
  the-hotfix-branch

Your current branch is highlighted with an asterisk and a different color.

Use Status Command

The status command is a widely used powerful command that shows your current branch among other things. Enter:

git status

And the output will be something like this:

On branch master 
Your branch is up to date with 'origin/master'. 
 
Changes not staged for commit: 
  (use "git add <file>..." to update what will be committed) 
  (use "git restore <file>..." to discard changes in working directory) 
        modified:   docker-compose.dev.yml 
 
Untracked files: 
  (use "git add <file>..." to include in what will be committed) 
        .idea/ 
        Dockerfile 
        docker-compose.override.yml.bak 
 
no changes added to commit (use "git add" and/or "git commit -a")

The first line shows which branch are you on. The second shows your upstream branch if there are any set.

Use Your Bash Configurations

This part works for Bash on Debian-based Linux distributions like Ubuntu.

I am using bash on Ubuntu. When I’m on a directory, my bash will show me something like this:

mohammad@pc:~/Dev/my-git-project$ 

So, all the time, I know which user account I’m using, on which host, and where on that host. It would be also very useful if your git branch would show up additionally. For it to happen, open your .bashrc file using your editor of choice:

vim ~/.bashrc

And add the following line to the end of the file:

PS1="${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\[\e[91m\]\$(__git_ps1 ' [%s]')\[\e[00m\]\$ "

Save and exit. Now, open a new terminal (or type source ~/.bashrc) and the git branch will show up whenever you’re in a git repository:

mohammad@pc:~/Dev/my-git-project [master]$

Conclusion

Try to configure your shell to show the git branch, it saves you a lot of time.
