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: "Select the Deploy from a file or URL option."

A block of code is set as follows:

Writing inode tables: done
 Creating journal (32768 blocks): done
 Writing superblocks and filesystem accounting information: done
 
 This filesystem will be automatically checked every 28 mounts or
 180 days, whichever comes first.  Use tune2fs -c or -i to override.

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

sudo rm /etc/localtime
sudo ln -s /usr/share/zoneinfo/UTC /etc/localtime

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: "Select the Deploy from a file or URL option."
