Linux Fundamentals Course Overview
This Linux Operating System and Bash Shell Programming training course introduces the delegate to the main concepts of the LINUX Operating System. The most commonly used commands are described in detail as are the command line wildcard and redirection facilities. The mechanisms by which a user acquires a login environment are discussed and the main features of the Bash shell are introduced.
The course is designed to give delegates practical experience in developing and writing shell scripts. Most of the built-in Bash shell commands are introduced together with the main program control structures.
The delegate will learn and acquire skills as follows:
- Creating, copying, renaming, moving and deleting files and directories
- Using the shell's redirection and pipe facilities
- Editing text files using the vi editor
- Setting and changing access permissions on files
- Monitoring and controlling their own processes
- Using the basic file and text searching utilities
- Customising their own login environment
- Writing simple scripts to enhance basic command output
- Using the various shell quoting mechanisms appropriately
- Manipulating shell variables and user-defined variables in scripts
- Implementing conditional execution facilities
- Using the shell's built-in loop constructs where appropriate
- Writing scripts to trap user interrupts
- User defined Functions
- Developing menu-driven shellscripts
Who will the Course Benefit?
There are no formal pre-requisites for the Linux Fundamentals course, although an understanding of and exposure to information technology is advantageous.
Programmers, administrators and support personnel who need to understand the LINUX Operating system, existing shellscripts, automate procedures and write their own utilities.
Course Objectives
To provide the skills needed to work productively in a LINUX environment to develop and customise shell programs.
Examinations
This course helps delegates prepare for the following exam:
Linux Essentials (LPI, exam 010-150)
This course, together with the Linux System Administration (LPI & CompTIA) course, helps delegates prepare for the following exams:

Course Reviews
The course is very good and I now have a better understanding of Linux. The lecturer was excellent. I would recommend this course to anyone who is interested in learning the fundamentals of Linux.
David - Platform Support Analyst - IT - March 2018
Lots learned from the course as I came here with very limited Linux knowledge, the pace and content were fantastic and I will be taking this new knowledge away with me and implementing as required in the work environment. Fantastic tutor that makes you feel at ease with the subject.
Neil - I.T. Systems Support Engineer - Communications - January 2018
Excellent instruction. He did a great job at targeting the content toward varying levels of ability.

More Course Reviews....
A very well presented course delivered at an appropriate pace for those attending. The instructors knowledge was excellent and his passionate delivery kept me engaged. The course notes for me are a real winner, as I only have occasional use of Unix at work I am sure I will forget much of this week before I am due to use it again, but the way in which the course notes are presented is both logical and functional and I am sure I will use these many times in the future.
Neal - Defence
I thought the course was very good and well structured. The instructor was always engaged and very knowledgeable and had answers to the questions we had and gave real world examples of what we were learning. I feel more confident now to be able to manage the systems we support as I understand them better. The last two days was brilliant and made understanding bash scripting much easier. Thank you very much.
Zubair - Technical Analyst - EPSD - Academic
Course content was good - tutor's knowledge was extensive and he provided extra tips and tricks - very useful! Would recommend this course.
