First off, I shamelessly stole this from http://www.bramschoenmakers.nl/en/node/624 But I wanted to be able to find it quickly

• ssh into your Homestead vagrant box
• Update the Ubuntu packages with sudo apt-get update
• Install bash-completion with sudo apt-get install bash-completion
• Open up your .bashrc file by with vim ~/.bashrc
• Toward the top (somewhere above where the PS1= is) add this

# Bash completion
if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
fi
export GIT_PS1_SHOWDIRTYSTATE=1

(The if statement checks on if the package installed)

• On the way down the page, might as well uncomment force_color_prompt=yes (remove the hash from the first character of the line)

• Below that you will find

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

You will need to add in PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[01;33m\]$(__git_ps1)\[\033[01;34m\] \$\[\033[00m\] ' which for me looks like

if [ "$color_prompt" = yes ]; then
    #PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
    PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[01;33m\]$(__git_ps1)\[\033[01;34m\] \$\[\033[00m\] '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

when I am done.

• Save that file and at the prompt type source ~/.bashrc to reload it.

• If you go into a directory with git you will see what branch you have checked out as well as a + if there are files to add (git add --all) and a * if there are uncommited files (git commit -m ':cake:')

There you go!
