Shell Script

In this article of the shell scripting tutorial series, we’ll learn how to create and use variables in shell scripts. We’ll walk through the different variables that we can make use of that are provided by the system for the Bourne Shell and how to create custom variables to use throughout a shell script. Variables

In the previous shell scripting tutorial, we worked with simple variables in shell scripts. Today we’ll cover arrays in shell scripts, and how we can create and make use of arrays within our scripts. To declare or create arrays on the fly, we will use the declare command (more explicit) or directly write array_name=(element1 element2

In our previous tutorial, we learned the use of the while loop in shell scripts. Now, let’s make use of the break and continue statement in Linux and manipulate the flow of loops. As we know, a loop will end if the condition supplied to it becomes FALSE. But what if you’re running a loop

After learning the basics in our previous tutorials about if-else statements, switch-case statements, etc, it’s time to create functions in shell scripts. Functions help us divide scripts into different sections and make the code more portable as well as reusable. Defining Functions in Shell Scripts The basic syntax for defining a function is just the

Continuing our series, in today’s article, we’ll go over the until loop in shell scripts. We’ve already covered for loops and while loops in shell scripts in our previous tutorials. You’ll find a lot of similarities in the while and until loop so we’ll also look at the differences between both the loops in this
