My personal .bash_profile file on my Mac. It styles my bash prompt in a way I like and also adds some useful alias.

.bash_profile

# ~/.bash_profile

[[ -s ~/.bashrc ]] && source ~/.bashrc

export CLICOLOR=1
export LSCOLORS=GxFxCxDxBxegedabagaced

alias subl='/Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl'
alias ls='ls -GFh'
alias ll='ls -l'
alias ddu='sh ~/Dropbox/Development/Themes\ WordPress/dobsondev-underscores/ddunderscores-osx.sh'
