How do I show the git branch with colours in Bash prompt?

  • 772

I am using this guide to show the branch name in gnome terminal (Ubuntu 15.10) when working in a git repository. Based on the above I now have the below in my ~/.bashrc file:

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes

...

# Add git branch if its present to PS1
parse_git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '
else
 PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi
unset color_prompt force_color_prompt

As a result I now get:

so it works. But why has the coloring of my user@host been removed? And I would also expect that the branch name should be colored. Before it looked like this:

UPDATE: I have now tried this guide instead:

https://coderwall.com/p/fasnya/add-git-branch-name-to-bash-prompt

adding this to .bashrc:

parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h \[\033[32m\]\w\[\033[33m\]\$(parse_git_branch)\[\033[00m\] $ "

and that works:

enter image description here

Notice in .bashrc I also have this (default):

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes

I have yet to find the reason why that snippet gives the correct result and the other version does not. Any input on this?

Here is the version of my .bashrc that has the old snippet enabled that does not work:

    This snippet:

    # Add git branch if its present to PS1

parse_git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '
else
 PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi

    Is meant to replace the default prompt definition:

    if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

    Which ends with:

    unset color_prompt force_color_prompt

    The .bashrc you posted shows you're adding it after the default prompt definition and unset color_prompt force_color_prompt (line #64).

    Either replace the default prompt definition with the snippet or leave your ~/.bashrc as it is and comment the default prompt definition along with unset color_prompt force_color_prompt on line #64:

    So part of your .bashrc could look like

    parse_git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\] $(parse_git_branch)\[\033[00m\]\$ '
else
 PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi
# THE SIX LINES BELOW are the default prompt and the unset (which were in the original .bashrc)
#if [ "$color_prompt" = yes ]; then
#    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
#else
#    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
#fi
#unset color_prompt force_color_prompt

  2. Ubuntu: Show your branch name on your terminal

    Add these lines in your ~/.bashrc file

    # Show git branch name
force_color_prompt=yes
color_prompt=yes
parse_git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '
else
 PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi
unset color_prompt force_color_prompt

    Reload the .bashrc file with this command:

    $ source ~/.bashrc

  3. For now, I followed this https://gist.github.com/eliotsykes/47516b877f5a4f7cd52f and working, liking it so far, though I'm planning to customize it further.

    In Terminal

    mkdir ~/.bash

    Copy the raw git-prompt.sh file from git contrib in to the ~/.bash directory: https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh

    Inside ~/.bashrc or ~/.bash_profile (choose the file where you normally put any bash customizations/setup), add the lines:

    source ~/.bash/git-prompt.sh # Show git branch name at command prompt
export GIT_PS1_SHOWCOLORHINTS=true # Option for git-prompt.sh to show branch name in color

# Terminal Prompt:
# Include git branch, use PROMPT_COMMAND (not PS1) to get color output (see git-prompt.sh for more)
export PROMPT_COMMAND='__git_ps1 "\w" "\n\\\$ "' # Git branch (relies on git-prompt.sh)

    As long as you're inside a git repo, your Bash prompt should now show the current git branch in color signifying if its got uncommitted changes.

  4. Quick hack:

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

export PS1="\u@\h \[\e[32m\]\w \[\e[91m\]\$(parse_git_branch)\[\e[00m\]$ "
    1. Restart the terminal, or source ~/.bashrc:

  5. Append the lines below to ~/.bashrc:

    export GIT_PS1_SHOWDIRTYSTATE=true
export GIT_PS1_SHOWUNTRACKEDFILES=true

export PS1='\[\033[32m\]\u@\h\[\033[00m\]:\[\033[34m\]\w\[\033[31m\]$(__git_ps1)\[\033[00m\]\$ '

  6. Go to home folder

    click Ctrl+h to show hidden files.

    Open .bashrc file and at the end paste the next:

    parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h \[\033[32m\]\w\[\033[33m\]\$(parse_git_branch)\[\033[00m\] $ "

    In case you have your terminal opened, close and open again. Enjoy!!

  7. I use bash-git-prompt. It's configurable and easier than writing your own, which I imagine is what many readers are looking for.

  8. Why bother with using sed? as in ...

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

    Much easier to just use:

    git branch --show-current

    It outputs the current branch and no extra characters!

  9. Topic is old but I will post being able to help someone. In the .bashrc file located inside the user's local folder, replace the existing PS1 with this one:

    if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\[\033[1;36m\]$(__git_ps1 " (%s)")\[\033[01;34m\]$\[\033[00m\]'

    If you want to change the color of the branch change the color before the parameter $ (__ git_ps1 "(% s)") that is, change this value:

     \[\033[1;36m\]

  10. My variant for KUbuntu 20.04 LTS, derived from the original value of the PS1:

    # put into ~/.bashrc
parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[33m\]\$(parse_git_branch)\[\033[00m\] $ "
