Shell Scripting: Expert Recipes for Linux, Bash, and More

Conventions

To help you get the most from the text and keep track of what’s happening, we’ve used several conventions throughout the book.

• We show commands like so: echo hello.
• We show system output and prompts like this: hello.
• We show file names and code within the text like so: /etc/hosts.

We present code in two different ways:

We use bold monofont type to emphasize text that is typed in by the user.
We use a monofont type with no bolding for code content and for system output.
