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: "If you keep a working copy of the svn repository, you may do this easily by executing the following commands inside that directory."

A block of code is set as follows:

    if http.page_exists(data, req_404, page_404, uri, true) then
   stdnse.print_debug(1, "Page exists! → %s", uri)
   end 

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

$svn co --username guest https://svn.nmap.org/nmap 

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: "You should see the message NMAP SUCCESFULLY INSTALLED when the operation is complete."

Warnings or important notes appear in a box like this.

Tips and tricks appear like this.
