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: “The application gets installed by default in C:\Users\<username>\AppData\Local\Programs\Microsoft VS Code and is only available for the user who installed it.”

A block of code is set as follows:

$x = 5
if ($X -gt 4) {
    Write-Output '$x is bigger than 4'
}

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

$Array  = 1,2,3,4,5
switch ($Array) {
    1 {Write-Output '$Array contains 1'}
    3 {Write-Output '$Array contains 3'}
    6 {Write-Output '$Array contains 6'}
}

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

sudo apt update
sudo apt install ./<filename>.deb

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: “On the Select Additional Tasks dialog, decide whether you want a desktop icon and file and directory context menu options, enabling you to open files and folders directly in VS Code.”
