This Linux video training course with Shawn Powers covers the exam objectives for the LPI Linux Essentials certification, an entry-level cert for those with no prior Linux experience.
Basic familiarity with Linux and/or non-Linux computer usage
Desktop or laptop system running Windows, OSX, or Linux
Virtualization software for installing and running Linux
LPIC-1 (Linux Professional Institute)

Linux Essentials is an entry-level certification designed for those interested in learning about Linux, but not quite ready for the LPIC-1 exams. While not a requirement for future LPIC-1 certification, Linux Essentials is designed to be a natural first step toward the more advanced certs.
This certification course is ideal for system administrators who want to delve into the world of Linux. Whether your goal is to advance to further certification courses, hone existing skills, or just learn enough about open source to make wise decisions in the server room, you'll find the information you need in this course.
1. Intro (00:02:18)
Linux is exciting technology that's crucial to any system administrator. Let's get the party started!
2. Linux Evolution and Popular Operating Systems (00:16:31)
This Nugget teaches knowledge of Linux development and major distributions. We learn about Open Source philosophy, distributions, and embedded systems.
3. Major Open Source Applications (00:14:14)
Linux is compatible with many applications, and in this Nugget, we learn about various major applications and their uses. This includes desktop, server, mobile, development, and package management applications.
4. Understanding Open Source Software and Licensing (00:22:18)
Licensing is what makes Linux so unique when compared to commercial operating systems. In this Nugget, we learn about the Free Software Foundation and the Open Source Initiative. The Linux community tends to throw around a lot of acronyms, so let's clear some of them up.
5. ICT Skills and Working in Linux (00:22:58)
Basic Information and Communication Technology (ICT) skills are important when working with Linux. In this Nugget, we learn about the Linux desktop, the command line, cloud computing, and virtualization. If you don't know a console window from a terminal session, this Nugget is for you!
6. Command Line Basics (00:21:45)
While the Linux desktop provides a very robust GUI with a wide variety of graphical applications and tools, the command line is where a system administrator spends most of his/her time. In this Nugget, we learn about the shell, variables, globbing, quoting, and a handful of useful command line tools that every sysadmin should know.
7. Using the Command Line to Get Help (00:20:47)
While grumpy sysadmins will often shout, "read the manual!," it's not often clear how to actually go about doing that. Thankfully, Linux provides a robust collection of documentation built right into the system. In this Nugget, we learn about documentation, man pages, and how to find the information you need when you need it.
8. Using Directories and Listing Files (00:18:32)
The Linux filesystem is set up much differently than Windows. If you're unfamiliar with Unix-like directory structures, it can be overwhelming. In this Nugget, we learn common conventions, file locations, and how to work with them on the command line.
9. Creating, Moving, and Deleting Files (00:17:16)
Once the filesystem is understood, manipulating those files is the next logical step. In this Nugget, we learn how to create, move, copy, and delete files and directories on our system.
10. Archiving Files on the Command Line (00:25:31)
With Windows systems, the most common archive format is Zip. On Linux, the options are a bit more plentiful, but all can be manipulated on the command line. We will learn how to create and extract tar, zip, gzip, and bzip2 files.
11. Searching and Extracting Data from Files (00:34:25)
As our Nuggets are demonstrating, the command line is very important in a Linux system. In this Nugget, we learn how to deal with data directly, using pipes, I/O redirection, and regular expressions.
12. Turning Commands into a Script (00:21:26)
Much like Windows batch files, Linux can script together a list of command line tools into a simple program. In this Nugget, we learn some simple scripting tools such as loops, variables, arguments, and shells. From starting the text editor to executing the final script, this Nugget is a crash course on Linux scripting.
13. Choosing an Operating System (00:21:04)
Every operating system (Linux, Windows, OSX) has its advantages, disadvantages, and purpose. Even Linux distributions have various strengths and weaknesses depending on their intended purpose. In this Nugget, we learn about the differences.
14. Understanding Computer Hardware (00:23:56)
Modern Linux works on a wide variety of computer hardware. In this Nugget, we learn the components that are required to build a system from scratch.
15. Where Data is Stored (00:20:18)
Building on our filesystem Nugget, we learn where various types of data are stored on a Linux system in this Nugget. Library files, system logs, bootloader code, and package management files all live in specific places.
16. Your Computer on the Network (00:23:05)
It's certainly possible to run Linux in stand-alone mode disconnected from a network, but it's not very common. Linux thrives on a network, and in this Nugget, we learn the basics of Linux networking.
17. Basic Security and Identifying User Types (00:14:12)
Linux users are all the same at first glance, but user accounts, system service accounts, and even the root account have different properties and different roles. In this Nugget, we straighten out user types.
18. Creating Users and Groups (00:13:29)
Expanding our understanding of system users, we learn to create users and groups. Using a handful of command line tools, managing local users is relatively painless. In this Nugget we learn how.
19. Managing File Permissions and Ownership (00:28:49)
In this Nugget, we learn about file permissions and ownership. The Linux permission system is elegantly simple and in this Nugget we learn how to determine and assign various permissions to files and folders.
20. Special Directories and Files (00:15:27)
In addition to file locations and permissions, there are a handful of special directories, files, and permissions. In this Nugget, we learn where they are and what makes them special!
