Unix/Linux Introduction

Linux is everywhere, and it's difficult. Make sure you know it.
Overview

Linux is almost the only operating system used on both small devices (IoT), and very large computers. Interested in Cyber Security? The only tools professionals ever use for Penetration Testing all run on Linux (Kali, Parrot).

Every year, Microsoft incorporates more Linux into their offerings. Windows 10 can natively run many Linux apps (via Windows Subsystem for Linux). .NET applications are now expected to also work on Linux machines (via Docker containers). So even if you're a Microsoft kind of guy (Admin or Dev), you'll need solid Linux skills. Linux is predominantly command-line driven, with awkward and often obscure commands. Consequently, it's super easy to make mistakes. This course will teach you what you need to know to avoid mistakes and learn to love Linux. Our Linux courses are always delivered on a fully up-to-date version of Linux (usually CentOS), but also always cover the differences between the major Linux distros (Red Hat Enterprise RHEL, Fedora, Debian, Ubuntu, Kali, Mint, SUSE etc.)

Purpose of this course

The course takes the novice user through their tentative first steps in the Unix/Linux command line, demystifying the inner workings and explaining why Unix/Linux does things in a certain manner. After only two days, delegates will have a good grasp of all Unix/Linux fundamentals.

Who is this course for

The course is suitable for those who are exposed to Unix/Linux systems in the workplace and will need to manipulate those systems in some way - anyone from casual desk workers, systems operations, support staff including those intended to support services (databases or networking services) that reside on a Unix/Linux platform.

You will learn how to
  • Become more familiar with the Unix/Linux environment
  • Understand the concepts behind the Unix philosophy
  • Grow in confidence with making Unix/Linux productive
  • Understand the hidden capabilities of Unix/Linux
Benefits for your organisation

Unix/Linux can be daunting and non-intuitive to the beginner, accounting for many hours of lost productivity due to frustration at trying to achieve even the simplest task during a support situation. By growing confidence and familiarity with this powerful operating system, employees can quickly produce results quicker and easier, translating cryptic command-level text into business-focused value.

Benefits for you as an individual

Unix/Linux-based operating systems are incredibly powerful and capable of a great number of things, many of which are hidden to the novice user.  Once you are exposed to its inner workings, you will tame this ferocious beast and make it work for you - and not be bitten by it any more.
