Why Different Commands ?

[th3james]

I assume you mean why are these commands differnt from the commands you
would use to run programs?

Basically, everything a computer does is done at terminal level, and
the graphical programs you run, provide a more attractive, easier to
use 'front-end' to the same commands, for instance:



Synapic package manager (System -> Administration -> Synaptic package
manager) is simply a graphic front end to Apt-get



as for the commands

sudo = allows you to perform any commands following it with
administrative priviledges (root)

apt-get = allows you at add, remove, and update programs

chmod = changes the permissions of a file (read, write, execute)

mkdir = simply MaKe DIRectory, the equivalent of creating a new folder



I hope this has been helpful
