Shell Scripting Tutorial

Hello Programmers, I’m Yash. Sole programmer at planetvearcity – a place where programmers come to learn, build, and grow.

Welcome to the tutorial series on shell scripting. In this video, we will cover variables.

The definition of a variables-a chunk of memory to which we can allocate values, interpret and manipulate its contents. Every programming language in existence has the concept of variables. There is no exception to the Bourne shell.

One thing to note is that when we declare variables along the way there should be no space around = sign. So let us get started.

The shell does not care about types of variables; they may store strings, integers, real numbers. Actually, these are all stored as strings.

Welcome to the tutorial series on shell scripting. In this video, we will cover comments and variables.

When writing Shell scripts, it is always a good practice to make your code clean and easily understandable. One of the ways to improve the readability of your code is by using comments. Adding comments to your scripts will make it easy for you to understand your code in the future. Let us go ahead and try using comments.

Comments are also useful when testing a script. Instead of deleting some lines, you can comment them out. If you are using a code editor like me then there is a shortcut to comment a given line or selected portion. In vs code its command plus forward slash.
