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: "To view the raw disk images on the iPhone, connect a jailbroken iPhone to a workstation over SSH and run the ls -lh rdisk* command."

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

iPhone4:/dev root# ls -lh rdisk*
crw-r----- 1 root operator 14, 0 Oct 10 04:28 rdisk0
crw-r----- 1 root operator 14, 1 Oct 10 04:28 rdisk0s1
crw-r----- 1 root operator 14, 2 Oct 10 04:28 rdisk0s1s1
crw-r----- 1 root operator 14, 3 Oct 10 04:28 rdisk0s1s2

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: "iOS provides an option Erase All Content and Settings to wipe the data on the iPhone."
