Place this in your .bash_profile for git-completion

git-completion-addons.bash

#
# Command line prompt addon, to autocomplete git commands & branches 
# as well as show current branch. It is especially useful since it modifies
# the terminal prompt & uses colors to distinguish if master is dirty
# or the working directory is up to date
#

# Step 1
# get git-completion.bash from any git repo 
# https://raw.github.com/git/git/master/contrib/completion/git-completion.bash

# Step 2
# open your .bash_profile and add the following one line
# source $HOME/bashs/git-completion-addons.bash

#
# Here is the contents of git-completion-addons.bash
# 
source $HOME/bashs/git-completion.bash

# color coding directories as brown, executables as red
export CLICOLOR=1
export LSCOLORS=DxFxCxDxBxbgedabagacad
