Introduction

At the core of each modern Linux computer is the “terminal.” The terminal developed from
the text-based computer terminals of the 1960s and 1970s, which themselves replaced punch
cards as the main method to interact with a computer. It’s also known as the command shell,
or just “shell.” In this unit, we will discuss some commonly used shell commands. Also we will
discuss some shortcuts and command line syntax.

8.1 Common Shell Commands

Linux consists of various commands and each command has its own set of options. All the
commands perform different operations. Now let us categorise all these commands as per their
function. By doing this, you will know the basic commands and have some measure of control
over the Linux command line.
