Conventions

In this book, you will find a number of text styles 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: "To launch fierce, we type fierce -h to see the help menu."

A block of code is set as follows:

if (argc < 2) 
    { 
        printf("strcpy() NOT executed....\n"); 
        printf("Syntax: %s <characters>\n", argv[0]); 
        exit(0); 
    } 

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

 fierce -dns host.com -threads 10

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "We right-click and navigate to Search for | All commands in all modules."
