How to configure command prompt in GIT with branch name. I get this error message: '-bash: __git_ps1: command not found'

Question

I´ve tried to get GIT to show me the directory and branch I´m working on. So that before I type in anything in GIT, when I´m in a project my command prompt would look something like:

project name (branch name) > 

I tried following a tutorial where I was told to make my .bash_profile in my ~ directory look like this:

#export PS1='jjberg '
alias ll='ls -lahG'

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

eval "$(rbenv init -)"

if [ -f ~/.git-completion.bash ]; then
  source ~/.git-completion.bash
  export PS1='\W$(__git_ps1 "(%s)") > '
fi

Problem is, whenever I type a command in GIT, an error message is always attached after every action has been performed. It looks like this:

-bash: __git_ps1: command not found

Does anybody have any idea on how I would fix this?

Won't you like to consider using ZSH? it will automatically detect git repositories just like what you want to achieve. It will look like something like this:

lan-chef-cookbooks git:(master) ✗

Btw, I'm using it on Macs but definitely there is a feature of autodetect the repository on other Linux/*nix distros.
