Could anyone explain why the branch name is not showing up on my (bash) prompt?

I am using ubuntu 16.10. I tried to use the instructions from this site.

# Git branch in prompt.

parse_git_branch() {

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

}

export PS1="u@h W[33[32m]$(parse_git_branch)[33[00m] $ "

My .bashrc file is here: https://github.com/JeremieGauthier/.bashrc/blob/master/.bashrc

I also tried the following code but it didn't work either.

function color_my_prompt {

    local __user_and_host="[33[01;32m]u@h"

    local __cur_location="[33[01;34m]w"

    local __git_branch_color="[33[31m]"

    #local __git_branch="`ruby -e "print (%x{git branch 2> /dev/null}.grep(/^*/).first || '').gsub(/^* (.+)$/, '(1) ')"`"

    local __git_branch='`git branch 2> /dev/null | grep -e ^* | sed -E  s/^\\* (.+)$/(\\1) /`'

    local __prompt_tail="[33[35m]$"

    local __last_color="[33[00m]"

    export PS1="$__user_and_host $__cur_location $__git_branch_color$__git_branch$__prompt_tail$__last_color "

}

color_my_prompt

At installation git comes with a git-prompt.sh that a bash function __git_ps1 to update the prompt.

The function is simple and add the current branch when you cd inside a git repo directory.

Just add a call to this function or another one available in your ps1 and make sure your .bashrc or your .bash_profile load the bash_completion directory.

If your version of git doesn't include the git_prompt.sh script manually download it and follow the instructions it provide.
