Command Line Fundamentals
Overview
From the Bash shell to traditional UNIX programs, and from redirection and pipes to automating tasks, Command Line Fundamentals teaches you all you need to know about how command lines work.
The most basic interface to a computer, the command line, remains the most flexible and powerful way of processing data and performing and automating various day-to-day tasks. Command Line Fundamentals begins by exploring the basics and then focuses on the most common tool, the Bash shell (which is standard on all Linux and iOS systems). As you make your way through the course, you'll explore the traditional UNIX command-line programs implemented by the GNU project. You'll also learn how to use redirection and pipelines to assemble these programs to solve complex problems. Next, you'll learn how to use redirection and pipelines to assemble those programs to solve complex problems.
By the end of this course, you'll have explored the basics of shell scripting, which will allow you to easily and quickly automate tasks.
