   What is sudo nano?  I would appreciate your help

[RGBKey]

sudo nano is a Unix command. sudo escalates your privileges to that of a super user, and nano is a simple, terminal based text editor. Used together, you can open up a text-based file for editing, including system files or other files requiring super user permissions.
