Description
This course is aimed to IT Pros or people who want to get familiar with Linux. And it's supposed to give the viewer the information they need to know to get started with command line to perform essential Linux administration tasks, including installation, establishing network connectivity, managing physical storage and basic security administration. It's a very-well structured course with step-by-step demonstrations, including lots of guided exercises, labs and quizes. The course is targeted to help to automate and script daily tasks. There are lots of live demonstrations how to use Bash commands. I hope it will help to do your job more efficiently. Here is some of the students' reviews: 'Thanks, instructor! It's a good structured course several hours long. I carried much useful information from it.'  – James K'simple and clear' –Swathi Mettu'Very useful for Linux Administrators' –DORDAA SUGLO RUDOLF'Great course!
