[Mac OS X] Creating a .bash_profile on your Mac Terminal

Look & Feel of the Terminal window can be modified in two ways:

First by opening the Preferences option available under Terminal Menu --> Preferences and make modifications to the layout settings of my choice.
Other option is using a .bash_profile. When you want to run functions from your command line, this is a must-have. Following steps will create a .bash_profile under the home directory.
  1. Start up Terminal
  2. Type "cd ~/" to go to your home folder
  3. Type "touch .bash_profile" to create your new file.
  4. Edit .bash_profile with your favorite editor (or you can just type "open -e .bash_profile" to open it in TextEdit.
  5. Type d following in my .bash_profile file:

    # Make ls use colors
    export CLICOLOR=1
    alias ls='ls -Fa'

    # define colors
    C_DEFAULT="\[\033[m\]"
    C_WHITE="\[\033[1m\]"
    C_BLACK="\[\033[30m\]"
    C_RED="\[\033[31m\]"
    C_GREEN="\[\033[32m\]"
    C_YELLOW="\[\033[33m\]"
    C_BLUE="\[\033[34m\]"
    C_PURPLE="\[\033[35m\]"
    C_CYAN="\[\033[36m\]"
