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

You can see them by listing files in long format, using the command '''ls -l''' in your working directory. It should look something like '''figure 5.1''', shown in MobaXterm.

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..."

So in this section we'll be doing just that.<br> Many of the commands you'll be learning in this course can receive data from the standard input and write to something called the standard output, so later in this section we'll introduce the concept of standard streams.

After having understood this, we'll do some work within a 'Unix ''command line interface (CLI)'' (exactly what a CLI is, we'll go into detail in the sections underneath) by using some basic Unix commands, some of which allow us to navigate throughout the file system.
