Video description

Have you tried to learn shell scripting on your own, but lack the structure you need to really improve your skills? Are you tired of picking up bits and pieces of information that you can’t just seem to put together? Do you learn best by doing? If so, you are going to love this course.

A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. One of the biggest complaints from students is that most of the courses they have taken in the past simply provide information without any context and without any idea of how to put that information to use. This course turns that old, frustrating, and outdated way of learning on its head. It is project-based, which means that instead of learning bits and pieces of information, you will write actual shell scripts that you can use in real-world situations. You get the chance to immediately put what you learn to use so that you fully understand and remember it.

By the end of this course, you will be able to write shell scripts that will allow you to work with Linux effectively.

What You Will Learn

  • Learn about using the proper permissions on your shell scripts
  • Learn to create and use variables in your scripts
  • Learn to use shell built-in commands and operating system commands
  • Learn to write scripts that execute commands on other systems
  • Learn to use command pipelining
  • Learn how to control all types of input and output

Audience

This course is for anyone who wants to master Linux shell scripting, bash scripting, and the bash shell. This can also be taken by any Linux system administrators, developers, or programmers.
