"Muito embora o Linux possua diversas e ótimas interfaces gráfica (GUI's - Graphical User Interfaces) bastante amigáveis, dentre as quais destacamos o Gnome e KDE, como de resto todos os sistemas operacionais Unix, ainda requerem por vezes que façamos uso da linha de comando.
O ambiente tradicional do Unix é o CLI (Command Line Interface), onde você digita os comandos para dizer ao computador o que ele deve fazer. Esse modo é extremamente poderoso e rápido, porém implica que você saiba para que serve cada comando e seus diversos parâmetros.” Usando essa página Essa página ira fazer você se familiarizar com os comandos básicos do GNU/Linux.

How to Create a Simple Shell Script on Linux. Shell scripts are short programs that are written in a shell programming language and interpreted by a shell process.
They are extremely useful for automating tasks on Linux and other Unix-like operating systems. A shell is a program that provides the traditional, text-only user interface for Unix-like operating systems. Its primary function is to read commands (i.e., instructions) that are typed into a console (i.e., an all-text display mode) or terminal window (i.e., all-text mode window) and then execute (i.e., run) them. The default shell on Linux is the very commonly used and highly versatile bash. A programming language is a precise, artificial language that is used to write computer programs, which are sets of instructions that can be automatically translated (i.e., interpreted or compiled) into a form (i.e., machine language) that is directly understandable by a computer's central processing unit (CPU).
