Conventions Used in This Book
Use this book as a reference. (Or use it as a decorative paperweight — whatever works for you.) Look up your topic or command in the table of contents or the index; they refer to the part of the book in which we describe what to do and perhaps define a few terms, if absolutely necessary.When you have to type something, it appears in the book like this:
cryptic UNIX command to type
Type it just as it appears. Use the same capitalization we do — UNIX cares deeply about CAPITAL and small letters. Then press the Enter or Return key (we call it Enter throughout this book). The book tells you what happens when you give each command and what your options are. Sometimes part of the command is in italics; the italicized stuff is a sample name, and you have to substitute the actual name of the file, computer, or person affected.Chapter 24 lists error messages you may run into, and Chapter 25 lists common user mistakes. You may want to peruse the latter to avoid these mistakes before they happen.
