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 are shown as follows: "For UNIX systems, the following command would suffice, assuming that the filename of the compressed image was installer.img.gz."

A block of code is set as follows:

export set MYSQL_HOME=/usr/local/mysql-5.5.18-osx10.6-x86_64
export set PATH=$PATH:$MYSQL_HOME/bin

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

sam@ubuntu:~$ ssh [email protected]
The authenticity of host '192.168.1.6 (192.168.1.6)' can't be established.
ECDSA key fingerprint is 55:36:12:f1:df:de:06:1a:7a:a4:36:b4:e1:09:a0:e2.
Are you sure you want to continue connecting (yes/no)?

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: "Check the option entitled "Share this folder" and give the share a meaningful name."
