Introduction to Linux Shells
Most users interact with operating systems through the Graphical User Interface (GUI), which involves a few clicks to complete tasks. However, you can perform nearly all operations by entering commands in the Command Line Interface (CLI). Shells enhance this command-based interaction, making it more efficient and resource-friendly.
Think of it this way: at a restaurant, you can either order from a menu (using the GUI) or cook your own meal (using the CLI). In this analogy, the kitchen represents the OS, and the shell provides guidance on how to prepare your dish. Using the CLI gives you greater power and control over your tasks.
Many Linux users prefer the terminal for executing commands, as seen in hacking scenes from movies. This room will teach you how to interact with a Linux shell, explore various shell types, and write shell scripts.
