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: "The mmcblk0p1 and mmcblk0p2 partition, respectively, relate to the first and second partition of the first block device (the number zero), whereas the mmcblk1p1 and mmcblk1p2 partitions relate to the second block device (the number one)."

A block of code is set as follows:

int main() {

  return 0;
}

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

mkdir ~/ubimage
sudo mount /dev/mmcblk0p2 ~/ubimage

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: "For this, go to the left-hand side window and open the Add menu with the green plus sign."
