Course Description

This course provides a comprehensive introduction to the full range of UNIX and LINUX user commands and utilities. Students will develop shell programming and vi editing skills as well as proficiency in using the command line. Beginners develop a solid foundation in Unix and Linux, while advanced users discover patterns and fill in gaps in their existing Unix knowledge.

Prerequisites

This course is suitable for End Users and Programmers who are new to the Unix or Linux Environment. Students should be comfortable with computers. No familiarity with Linux or other Unix operating systems is required.

 

Certification

this course will give you sufficient knowledge to take the Linux Essentials Professional Development Certificate. This is a newly revised certification and also serves as an ideal stepping stone to the more advanced LPIC Professional Certification track for Linux Administrators. It is a 60-minute exam containing 40 questions.

Study guidelines before sitting LEPD certificate: It is recommended that those who have little previous Linux experience prior to attending this course should assign a minimum of 16 hours self – study time before taking the Linux Professional Development certificate exam after completion of this course. The recommended self-study time is a general guideline and will vary depending on each learner and their prior Linux training and background experience in working with Linux.
