Linux Essentials for Developers (LED)


Course Overview

Linux is at the core of nearly all open-source projects. If you want to become a developer, then Linux is the engine that will run nearly all of your code. Your view of Linux will be different than a Linux System admin who must make sure that system availability is as close to 100% as possible. As a developer, you will be required to make Linux bend to your will, which is means you will have great power over the system. With great power comes great responsibility. You must be able to use Linux to accomplish your task, while not adversely affecting system reliability, security or operational efficiency. In this course you will learn how to make Linux deliver essential services and in the same motion, maintain the Linux system integrity. Successful students can generally expect their work efficiency to increase dramatically.

Outline: Linux Essentials for Developers (LED)

1. Navigating Linux - As a developer, you must understand the file structure. Your project will work only if you place files in the right place. Expect an epic fail if you do not follow the rules, so let’s start with housekeeping. Ignore this chapter at your own peril.

    • File naming convention - do and do nots
  • The dot files

2. Essential linux tools (Each of these will appear as a chaper in the course documentation)

  • vim - Edit files
  • tmux essentials - massively reduce keystrokes
  • htop - Is your code killing system performance? Here is a great way to know that answer
  • tail -f - Let the logs tell you what is failing
  • watch
  • bash shortcuts
  • Choosing a linux cheat sheet - We have several, choose the one that best helps you learn the essentials
