These computers are either desktop pc's, which is the type that you're using, or they're server computers. The internet in its entirety is in fact an example of humongous network of global proportions, so as a short introduction, watch this short and simple video explaining the internet [https://www.youtube.com/watch?v=7_LPdttKXPc What's the in..."

Processes are a fundamental concept of Linux systems and we'll start by discussing what can be termed as the life cycle of processes. This includes the concepts of parent and child processes and while going through this subject, we'll also introduce some essential commands that allow us to view ongoing processes in our terminal. These commands are '''ps''', '''jobs''' and '''top'''. Next we discuss foregr..." current

These file extensions mean that the file is compressed and file byte size reduced so that it requires less disk space. Bytes are simply a sequence of 8 bits, and we've previously seen how this is used to store ASCII characters. Files that have been compressed can also be decompressed, making them user readable but requiring more bytes on..." current

In this section, we'll be learning so-called ''filter commands'', some of which utilize regular expressions in order to find and replace patterns. It is therefore important to have a basic understanding of regular expressions. To get you started, follow this link to an introductory video, [https://www.youtube.com/watch?v=KJG1dETacLI B..."

These shell scripts contained multiple commands and the script could be executed with '''bash'''. In this section, we go through some of the basics of shell scripts. Before getting started, however, you should know that when writing shell scripts in text editors, it's important that it supports bash. For example, running Sublime on the Windows OS will cause errors. If you're using Vim editor, you should have no p..." current

Text editors are used for editing files and there are many text editors to choose from. You've probably already used some text editors, like ''Notepad'' or ''TextEdit'', as these are the default text editors on a Windows or Mac OS. In this section, we'll be taking a look at a lot..."
