Mastering CLI Basics

Overview

This lab introduces you to the fundamentals of the Command-Line Interface (CLI) and its role in DevOps workflows. You will explore essentials such as navigating the file system, managing files and directories, accessing documentation, and mastering pattern matching using wildcards. By the end of the lab, you'll develop efficient workflows using commands, flags, shortcuts, and wildcards, boosting your productivity in DevOps operations.

Inside this Lab

In this comprehensive lab:

• Understanding CLI Basics: Learn the structure and importance of the CLI, distinguish between shells and terminals, and execute basic commands to understand shell behavior.
