Master scripting in Bash, Python, and Ruby in one single courseAbout This VideoThe course has been divided into 3 section, with each section going over one particular language.You'll learn the fundamentals of Python programming language in the second section which includes its basic concepts such as lists, loops, conditions, dictionaries, modules.In the third section, we'll go over the basics of Ruby and cover some concepts in detail such as quoting, interpolation, arrays, hashes, code blocks, modules, etc.In DetailMaster the art of scripting with these popular languages in this comprehensive beginner's course! The first thing any DevOps engineer learns is a scripting language to navigate through devices, software and servers. These are exceptionally powerful and are the basics of learning development. We will break down each language to help you master the fundamental concepts that the language is built on. The 3 languages that are covered are Bash, Python and Ruby. Bash is a scripting language commonly used for programming in Linux. Linux scripts are used for automating certain programming tasks. They can also be used to simplify complex tasks and also help solve real-world problems. While learning how to write scripts is easy, it is a little more difficult to write good and effective scripts. In this course, we focus on exactly that. We will show you how to write amazing scripts that can not only reduce repetitive tasks, but also can be integrated into your real-world projects. Python is another popular programming language that is commonly used for back-end development. An amazing feature of Python is that it allows you to do much more using fewer lines of codes. This course focuses on helping you learn exactly how to get the most out of Python. Lastly, we will focus on Ruby. Ruby is a dynamic programming language that focuses on simplicity and productivity. It was designed to support multiple programming paradigms, including functional, object-oriented, and imperative. It is used for building apps and websites on Linux and UNIX. This includes writing basic scripts, important syntax rules, automating tasks using code snippets and even writing codes for building actual products. At the end of this course, you will have not only mastered three powerful programming languages, but you'll also be comfortable enough to actually start writing simple programs using these languages.
