Need some help with Terminal

use pico

Code:

sudo pico /etc/hosts

 

pico is a symbolic link to nano, so your post adds nothing.

 

As you indicated, do sudo nano /private/etc/hosts in Terminal and supply your password if requested to do so.

Use down-arrow key to move cursor to below existing lines, and then type in what you want to add. Press control-o to save (ie, WriteOut) and then control-x to exit.
