Product Description
This book introduces the Unix command line interface to users. Unix originally supported only a command line interface. Though most Unix systems now support GUI interfaces, all are based on the original command line interface. Many people still find it easier to use the command line for operations. Instead of trying to figure out how to click through a GUI interface to do a certain task, you just have to type a few words. The focus of this book is on users, describing user tools and applications for the command line, not administration tasks. The text is organized to carefully introduce you to Unix without overwhelming you with a mass of commands and programs. In Part 1, you learn how to get started using the command line interface. In Parts 2 and 3, you learn essential features of Unix needed to perform everyday tasks such as file management and shell operations. Together, Parts 1, 2, and 3 form a core level of understanding that you need to have in order to successfully work with Unix. Parts 4, 5, and 6 consist of topics that you can select depending on your needs, such as data and edit filters, awk programming, email, Ftp access, and editors.
