Conventions used

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

CodeInText: 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 WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

#!/bin/bash
printf 'Starting script\n' >> log
printf 'Creating test directory\n' >> log
mkdir test || exit
printf 'Changing into test directory\n' >> log
cd test || exit
printf 'Writing current date\n' >> log
date > date || exit

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

$ printf 'Hello, world\n' > myfile $ ls -l myfile -rw-r--r-- 1 bashuser bashuser ...
