This course is a concise crash–course into Linux and MacOS Shell. Although it is short, it introduces you to a number of commands to interact with files and directories, and build a chain of commands into pipelines: ls, cp, chmod, grep, find, less, head and even more. Whether you are in an urgent need to get familiar with common shell commands, or want to take your time and discover command line interface, this course will help you to get started.
What is Command Line Interface (CLI, or just Shell)? Wikipedia says, it is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines). A program which handles the interface is called a command language interpreter or shell (computing) . Command Line gives you a great control over functions of the operating system, as well as the hardware of your computer, such as a network or a sound card. Many end user applications have a user interface that simplifies user experience, and if you want a better flexibility, the Command Line gives you this option.
Command Line Interface is the core of the operating system, it gives you access to the lowest level of interactions with it. This course will use Linux/Unix interface which is also available in MacOS: most of the commands used in the course are also available in MacOS.
