This book should be of interest to Unix users and Unix programmers, as well as to anyone (such as a system administrator) who might offer direct support to users and programmers. The presentation is geared mainly toward people who are already familiar with the Unix system; that is, you know what you want to do, and you even have some idea how to do it. You just need a reminder about the details. For example, if you want to remove the third field from a database, you might think, 'I know I can use the cut command, but what are the options?' In many cases, specific examples are provided to show how a command is used.
