Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "System is a reference to operating system and designates the scope of the role: managing the platform on which applications run."

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

$ lvcreate -l 100%FREE -n lv_data vg1

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "As we progress through our exploration of Linux System Administration, the idea of hats and really digging into job roles and functions will become more and more clear."
