“There is a short list of commands that one can learn to get
started. With this short list, you can begin to build your toolbox
and with the help of a few good reference sites, become a command
line master yourself. Not only will this enable you to feel
comfortable running just about any Linux distribution available,
but every programmer working today began with that first
command.“But how might one go about trying to use the dreaded command
line? Once open, the user stares at the prompt wondering what to do
first. They know folks work from the command line all day every
day, but what do you do? Fortunately, you’re not on your own. There
are a plethora of sites with all the information you’ll need to
take you from beginner to advanced user or anywhere in
between.”
