Basic setup for bash

.bash_profile

# bash.profile

# .bash_profile is executed for login shells                                                    
# .bashrc is executed for non-login shells
# However, Mac OS X’s Terminal.app runs a login shell by default for each
# new terminal window, calling .bash_profile instead of .bashrc
if [ -f ~/.bashrc ]; then
  source ~/.bashrc
fi

# bash.rc
export CLICOLOR=1
