If you are missing colors in the terminal / console, (and the 'l' shortcut command) here is how to fix that.
Open your ~/.bashrc file in an editor
vim ~/.bashrc
and add the following at the bottom
alias ls='ls --color'
alias ll='ls -alF --color'
alias l='ll'
This adds 3 aliases. It makes ls display colors by default and also defines useful shortcuts - ll and l.
Save the file (in vim, press escape, followed by :wq and press enter).
In the terminal, run source ~/.bashrc to apply the changes.
