We are about to delve into shell scripting. Shell scripts are used to automate certain things related to files.

It is good to be acquainted with shell scripts if you are a software developer, but if you are a regular user, read this only if you are interested. The aim of this section will be to get you familiar enough with shell scripting to read and write shell scripts, albeit you will need to Google certain details of the things you are trying to achieve (if you are writing your own shell scripts). We will do this by making a very simple shell script which demonstrates the usage of each of the constructs we will learn to use.

Moving on, we will talk about how Linux boots up, how it shuts down and about init – the process with which it all begins. Wow, I feel like I’m watching Lord of the Rings or something.

This is good to know because if you ever encounter any issues with any one of the things during boot-time, it will be useful to know where things went wrong and to have context on it.

Next up, we will talk about devices at a low-level. More specifically, we will talk about how are devices represented in your Linux system, what are links, what is mounting, what is unmounting and some other things related to devices which are not as important, but warrant a quick read.

This is not really important for your everyday use, but you will almost guaranteed encounter some device-related things (especially if you are a software developer), so it pays to know these things in those moments. And yes, even if you are a regular user, it pays to know these things. So read on. Don’t lose your enthusiasm – you are still learning the fundamental things.

Going on, we will talk about file compression and commands related to package management. Both are used relatively frequently. If you are a “regular” desktop user, then using a graphical user interface (GUI) to compress and decompress archives is going to be enough most (if not all) of the time. Still do read through it, because sometimes you may have to use the command line and it pays to know what the tutorials you found on Google are telling you. In relation to package management, that is something you will use very frequently both as a regular desktop user and as a software engineer (or some other career choice) using Linux, so do pay close attention.

Moving on, we will learn about processes. We will talk about commands related to process monitoring and management and concepts relevant to truly understand process-related activities.

This is probably my favorite part, not only because it is fundamental to understanding the Linux operating system and operating systems in general, but because this was challenging to explain – to cull out what isn’t essential, but still give you the bigger picture. I hope that you will find it a joyful read.

Going on, we will talk about text editors. This is not that important to you if you are not a software engineer or someone other than a “regular” Linux user, like an aspiring information security expert or a “wannabe” system administrator. If you are just using Linux instead of Windows for everyday things, you don’t need this material, in my opinion.

Carrying on, we will talk about history and about variables. Understanding what variables are and how to manipulate them is essential. Understanding what important variables entail is also essential. Do make sure to pay attention.

In the following articles, we will talk about command types (not all commands are of the same type), some file-related commands and searching for files.

Searching for files is the thing you will use most often, but it pays to know what command types are there and how to see the difference between two files, for example. Make sure to pay attention to searching for files and do read through other content, but again, it isn’t going to be of that much importance.
