Welcome to the first step of your Linux command line training! In this lesson, we prepare your computer for hands-on learning by setting up a local Linux environment.
We guide you through installing Ubuntu—the industry standard for server and administration—using WSL for Windows or Multipass for Mac, ensuring you are ready to follow along with every command.
Unlock the true power of Linux by taking your first steps into the Linux command line.
In this lesson, we demonstrate why the terminal is the superior tool for server administration, guiding you through essential diagnostic commands like ps -ef for process monitoring and ping for network troubleshooting.
We also break down the anatomy of the command prompt and show you how to connect to remote systems on Ubuntu—proving that learning the command line is not only a vital skill but can also be surprisingly fun.
Master the syntax that makes the Linux command line so flexible. In this lesson, we break down the essential difference between arguments and options (flags), teaching you how to customize the behavior of commands like ping and ps.
We cover critical concepts including case sensitivity, combining multiple flags (like ps -ef), and using long-form options—foundational skills for effective Ubuntu server administration.
Stop trying to memorize every single flag and start mastering the ultimate resource: the Linux Manual Pages (man pages).
In this Linux command line lesson, we teach you how to read and understand technical documentation natively on your Ubuntu system.
We explain how to decipher the 'SYNOPSIS' section, understand syntax brackets, and effectively use the man command and -h help flags—essential research skills for independent server administration.
Work smarter, not harder, in the Linux command line. In this lesson, we focus on productivity hacks that every Ubuntu user needs to know.
Learn to leverage command history (including the history command and the !! shortcut), master Tab completion to speed up typing, and utilize essential keyboard shortcuts like Ctrl+A, Ctrl+E, and Ctrl+U.
These workflow efficiencies are crucial for rapid server administration and daily Linux use.
Transitioning from a mouse to the keyboard? This lesson covers the fundamentals of Linux navigation.
We explain the concept of the root directory, absolute paths, and the home folder.
By mastering commands like ls (list) and pwd (print working directory), you will gain the confidence needed to navigate the Linux command line, a critical first step for any future server administration tasks on Ubuntu or CentOS.
Unlock the power of movement within the terminal. In this lesson, we master the cd (change directory) command on the Linux command line, moving beyond the basics to understand the crucial difference between absolute and relative paths.
You will learn to navigate the file system hierarchy efficiently, utilizing shortcuts like the tilde (~). These navigation skills are the foundation for managing files on Ubuntu and performing essential Linux server administration.
In this Linux command line lesson, we embark on a grand tour of the Linux file system hierarchy.
You will learn the purpose of essential system directories—including /bin, /etc, and /usr—and how to identify executable and configuration files.
This knowledge is crucial for anyone looking to master Ubuntu or general Linux server administration.
Go behind the scenes of the Linux command line to discover exactly what happens when you type a command.
In this lesson, we demystify the core components of the operating system: the terminal emulator, the Bash shell, and the kernel.
You will learn how the shell interprets inputs on your Ubuntu server using environment variables like $PATH, providing you with the architectural knowledge essential for effective Linux administration.
Use the mv command in Linux to move or rename files and directories by changing their paths, noting that it overwrites existing files without warning.
Learn to compress and decompress files using gzip and tar, create and extract archives, and compare compression options for efficient Linux file management.
Verify file integrity with sha256sum, md5sum, and sha512sum to detect corruption. Explore hash properties, the one-way nature, and security implications, plus uses from software updates to password storage.
Master symbolic links, their advantages over hard links, and how to create them with ln -s, readlink. Learn to handle broken symlinks and choose absolute versus relative links.
Learn Linux file permissions and ownership to control read, write, and execute access. Understand owner, group, and others to secure files and directories.
Explore the linux root user and its unlimited access, the principle of least privilege, and how sudo enables temporary root commands for safe, controlled system administration.
Explore how Linux groups manage file permissions, with primary and secondary groups, group ownership, and secure access for users and applications, demonstrated through practical examples and a hands-on exercise.
Learn to securely grant access to files using dedicated groups. Apply group-based permissions with commands like groupadd, usermod -aG, and groupdel, and refresh sessions after changes.
Explore Linux application packages and the package system. Download and install a deb package with dpkg, then inspect where files go in /usr/bin, /usr/lib, and /usr/share.
Learn how package managers simplify installing, updating, and removing software, auto-handle dependencies, and keep your system healthy with apt and apt-get examples.
