On Linux (e.g. Ubuntu) the terminal shows you executables and folders and such in different colors so you can identify them easier. Is this possible on Mac OS Terminal, too?
To add color output of the ls command, you need to edit your ~/.bash_profile and add:
export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad
This is just an example, look at the ls manpage on how to change specific color values.
