Introduction to Linux

This course introduces the foundations of Linux from the command line, helping you understand how the operating system that powers most of the world's servers and cloud infrastructure actually works, and how to control it directly through the terminal. You'll begin by setting up your own Linux environment using a virtual machine or WSL2, then learn to navigate the filesystem with confidence — moving between directories, listing and exploring files, and locating anything using pattern matching and file discovery. From there, you'll create, move, copy, and link files and directories, and understand how the Linux filesystem and architecture fit together.The course then moves into reading and searching file content, where you'll inspect files, filter data, and run recursive searches across the system. Finally, you'll bring it all together with the tools that make the command line powerful: standard streams and output redirection, the pipe operator and command chaining, and a full text-processing suite including grep, sort, uniq, sed, and awk. By the end of this course, you will be able to: - Set up a Linux environment and navigate the filesystem from the command line. - Create, move, copy, and link files and directories using core commands. - Search and filter file content using pattern matching and regular expressions. - Manage standard streams and redirect command output and errors. - Chain commands together using pipes, tee, and command sequencing. - Process and transform text data using grep, sort, uniq, sed, and awk. Designed for complete beginners, aspiring system administrators, and developers looking to expand their skills, this course provides a solid foundation for everything that follows in Linux administration. No prior Linux experience is required — just a computer and a willingness to work in the terminal. Begin your Linux journey and discover how the command line gives you direct, powerful control over any system.
