Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded RHEL8.iso disk image file as another disk in your system."

A block of code is set as follows:

#!/bin/bash
echo "Hello world"

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[default]
branch = main
repo = myrepo
username = bender
protocol = https

Any command-line input or output is written as follows:

$ mkdir scripts
$ cd scripts

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Select System info from the Administration panel."
