Course Details

User Level Linux (ULUX) is an online training course designed to get you quickly up to speed on Linux from a user perspective. It will allow you to do the most common set of tasks on Linux in a very short span of time. The laboratory environment is based on Linux a free variant of UNIX. However, the course has been designed in such a way as to focus on the common commands and techniques across Unices such as AIX, HP-UX, Solaric etc. If you have heard the term Linux or GNU/Linux and want to learn this awesome operating system from the convenience of your home or office and at your own pace, then VirtuQ™ online training course (course) on Linux (or UNIX) is the way to go.

ULUX is a pre-requisite for taking up any course from VirtuQ™ because all our laboratories are based on Linux. Also, most of the high-tech industries rely on Linux for their operations. It is thus recommended that you take up this course and get to know it from a user perspective so that you are very comfortable working on it.

ULUX is divided into two parts. Part I focuses on the most common set of tools and utilities in Linux and part II focuses on programming and document formatting. It has 8 hours of theory and around 40 hours of laboratory exercises. However, the time may shrink considerably for users who are somewhat familiar with Linux or have otherwise done considerable scripting in windows.


  1. Strong focus on hands-on experience
  2. Insight into various design choices in Linux
  3. Familiarity with various programming and software engineering tools
  4. The concepts, commands, exercises follow POSIX standard, so that you are able to work equally well on any UNIX and not just Linux
  5. Discuss with the instructor on the forums as much as you want

Instructor and Forum Moderator

This course is taught by Anup Gangwar. He will also be moderating the course forums.


You only need to have basic familiarity with computers.

Who should take the course


ULUX course is a beginners+ course. It is not an advanced course, however subject treatment in the course is more than what a typical beginner level course will offer.

Detailed Description

Part I

Part I starts by offering insights into the original UNIX and windows design philosophies. Doing so allows us to understand the reasons for many of the design choices of Linux as we gain more insight into it. Next, it discusses how to do the common tasks in Linux. By the time you are done with this part, you should be very familiar with the most common set of commands in Linux. Detailed table of content is as follows.
