I just wanted to share with you how my terminal looks like and how to export the PS1 variable.
To achieve it for Ubuntu: sudo gedit ~/.bashrc
For Linux Mint: sudo gedit /etc/bash.bashrc
And paste the following there at the line before the last one:
export PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[01;33m\]$(__git_ps1)\[\033[01;34m\] \$\[\033[00m\] '
