Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "If a developer wants to see the application logs on the server, there is no need to give him full sudo permission."

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

Sent Message --> "Schedule Launch Date : 27 June 2017 "

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes, for example, appear in the text like this: "Once you click on Create Key, you will be asked to fill in a certain set of details."

Warnings or important notes appear in a box like this.

Tips and tricks appear like this.
