Display git branch in bash prompt

.bashrc

# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer!

export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ "

# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty!

# ~/code/web:beta_directory$ git checkout master
# Switched to branch "master"
# ~/code/web:master$ git checkout beta_directory
# Switched to branch "beta_directory"
# ~/code/web:beta_directory$ 

Works! Thank you! Ubuntu 20.4

@cheesits456 I really like yours, although it is a bit off in directories that aren't git, shows a lot of Chinese like markings, (lool and some numbers too, can I know what they stand for ? thanks ).
I think the first number is for folders, the next is for text files .....

@stealthman22 I just realized I never actually gave a proper answer to your question, sorry :P Nerd Font is a project that makes patched versions of popular fonts, replacing a ton of unused characters with icons - you can download one from https://www.nerdfonts.com/font-downloads, then put the ttf file in ~/.fonts, then set it as your terminal's font - once that's done, the icons will show up properly.

As for what they represent, I'll go left to right. The one that looks like a purple E becomes a filled left angle bracket once you apply a nerd font. Next to that is my OS icon - if you run something other than Arch, you can search your OS at https://www.nerdfonts.com/cheat-sheet and copy/paste the character into your .bashrc file in place of the Arch icon. After the username there's a filled right angle bracket, then your current directory in plaintext, then another filled right angle bracket. After that is a folder icon, then a number equal to the number of folders in your current directory. Then there's a file icon and a link icon, both with numbers beside them, which represent the number of files and symbolic links in your current directory, respectively. If you're in a git directory it'll show a git branch icon and print the name of your current branch. The rest of the icons from the nerd font are just more of the shaped icons for styling.

Here's a screenshot that shows the relation between the numbers and the types of files in the current directory:

Hope this helps <3

Here is mine PS1:

function parse_git_dirty {
  [[ $(git status 2> /dev/null | tail -n1) != "nothing to commit, working tree clean" ]] && echo "*"
}
function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/(\1$(parse_git_dirty))/"
}
export PS1='\[\e[\033[01;34m\]\u@\h \[\e[38;5;211m\]\W\[\e[\033[38;5;48m\] $(parse_git_branch)\[\e[\033[00m\]\$ '

My two cents..

@vuon9, I really liked your functions to shorten the directory path in the prompt.
However, since you defined the colors without the closing brackets, I found that whenever I brought back the previous command and tried to edit the command, I could not go back to the beginning of the line. There were a few dangling characters padding the left side of the command.

To fix that issue, I combined the prompt at https://gist.github.com/justintv/168835#gistcomment-3554316 from @cheesits456, replacing Nerd font characters with available emoji icons, to arrive at my prompt as below.

@nononsensetekkie oh wow, I got your point. I love the improvement too!!!

This is for Ubuntu but probably will work for other distros that use the DejaVuMono.ttf font as the default.
This is for those that don't want to fiddle with changing fonts, suggest this:

I created my own version for displaying the git branch in prompt starting from @vankasteelj reply (wrote on Mar 7, 2016).

It is a simple solution that includes branch status color. Take a look:

parse_git_bg() {
  if [[ $(git status -s 2> /dev/null) ]]; then
    echo -e "\033[0;31m"
  else
    echo -e "\033[0;32m"
  fi
}

PS1='\[\033[0;32m\]\[\033[0m\033[0;32m\]\u\[\033[0;34m\]@\[\033[0;34m\]\h \w\[$(parse_git_bg)\]$(__git_ps1)\n\[\033[0;32m\]\$\[\033[0m\]'

I'll leave this here:

PS1='\[\033[0;32m\]\[\033[0m\033[0;32m\]\u\[\033[0;36m\] @ \[\033[0;36m\]\h \w\[\033[0;32m\]$(__git_ps1)\n\[\033[0;32m\]└─\[\033[0m\033[0;32m\] \$\[\033[0m\033[0;32m\] ▶\[\033[0m\] '

WOOOW..Thanks a lot for this. :D

I edited mine to show whether there's uncommitted changes on the current branch

Probably the most rich solution I found so far: https://github.com/diogocavilha/fancy-git

I would like to see my python virtual environment (venv) as well, as it is usually the case when using MINGW64-git-bash.

So previously, the venv "projectname-venv" was shown in parentheses on the left, but after applying some fancy PS1-command to change the style, coloring and make the current git-branch appear on the right, the venv is missing afterwards.

(projectname-venv) andylu@hd1pcms0347:/mnt/c/Users/username/Projects/projectname$
PS1='\[\033[0;32m\]\u\[\033[0;36m\] @ \[\033[0;36m\]\h \w\[\033[0;32m\]$(__git_ps1)\n\[\033[0;32m\]└─\[\033[0;32m\] \$\[\033[0;32m\] ▶\[\033[0m\] '

andylu @ hd1pcms0347 /mnt/c/Users/username/Projects/projectname (feature/story-43052-dev)
└─ $ ▶ ls

I'd like to have a PS1-command including the venv.

@cheesits456

How do I let it display correctly?

Windows Terminal - SSH

@Lulalaby You need to set the terminal font to a nerd font (patched fonts that replace unused characters with different icons). You can get nerd fonts from https://www.nerdfonts.com/font-downloads. The one I'm using is FantasqueSansMono

thanks!

I just recently started using this and works perfectly.

git_branch() {

if [ git branch 2>/dev/null | grep '^*' | colrm 1 2 | wc -l -eq 1 ];
then
echo -n "("
echo -n git branch 2>/dev/null | grep '^*' | colrm 1 2
echo -n ")"
fi

}

PS1='[\033[0;32m][\033[0m\033[0;32m]\u[\033[0;36m] @ [\033[0;36m]\h \w[\033[0;32m] $(git_branch)\n[\033[0;32m]└─[\033[0m\033[0;32m] $[\033[0m\033[0;32m] ▶[\033[0m] '

This will not have () if there is no branch found.
And it will write with a () if there is a branch.

Optimization wrt slow prompt rendering :
How to make the prompt display INSTANTLY, whatever the complexity of the git state computation ?
-> by NOT performing any git state computation, UNLESS the working directory has changed, OR git command was run.

PROMPT_COMMAND='history1=`history 1`;
if [[ $PREVIOUS_PWD != $PWD || ( $history1 == *" git "* && $history1 != $PREVIOUS_CMD ) ]]; 
then GITBRANCH=`__git_ps1`;  # or whatever git state computation commands
fi; 
PREVIOUS_PWD=$PWD; PREVIOUS_CMD=$history1;'

PS1='\[\033[32m\]\u@\h \[\033[33m\]\w\[\033[36m\]$GITBRANCH\[\033[0m\]\n$ '
# or whatever prompt rendering, as long as it embeds $GITBRANCH which has been conditionally computed above

Could any of you share the fonts you are using in your terminals? Especially the ones with the file and folder icons?

-> by NOT performing any git state computation, when the working directory has NOT changed.

But then the prompt doesn't change when you switch branches.

-> by NOT performing any git state computation, when the working directory has NOT changed.

But then the prompt doesn't change when you switch branches.

You're correct.
So let's improve & rephrase the optimization :
"-> by NOT performing any git state computation, UNLESS the working directory has changed, OR git command was run."

I updated my original proposed solution accordingly.

I created my own version for displaying the git branch in prompt starting from @vankasteelj reply (wrote on Mar 7, 2016).

parse_git_bg() {

    echo -e "\033[0;31m"
  else
    echo -e "\033[0;32m"
  fi
}

PS1='\[\033[0;32m\]\[\033[0m\033[0;32m\]\u\[\033[0;34m\]@\[\033[0;34m\]\h \w\[$(parse_git_bg)\]$(__git_ps1)\n\[\033[0;32m\]\$\[\033[0m\] 

Based. Thanks.

1 as True or correct command, and if it is 0, then it is false or wrong.

parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'
}

export PS1="╭─╼[\[\e[1;36m\]\w\[\e[0m\]]-(\`if [ \$? = 0 ]; then echo \[\e[32m\]1\[\e[0m\]; else echo \[\e[31m\]0\[\e[0m\]; fi\`)-[\[\e[1;32m\]\h\[\e[0m\]]\n╰─ \u\$(if git rev-parse --git-dir > /dev/null 2>&1; then echo '@git:('; fi)\[\e[1;34m\]\$(parse_git_branch)\[\e[0m\]\$(if git rev-parse --git-dir > /dev/null 2>&1; then echo ')'; fi) >> "
