This book describes the UNIX operating system user commands. It is based on AT&T UNIX System V Release 4 and Berkeley Software Distribution(BSD) 4.3. It provides you the knowledge and insight to fully use the power of the UNIX System.
You may ask what exactly is UNIX? UNIX is several things. It is a computer operating system. It is also a large set of utility programs. These utilities include general user, programmer, typesetting, communication, and administrative commands.
Because UNIX is a large computer operating system environment, only the more popular User Commands (over 160) will be discussed. An overview of the UNIX System, an MS-DOS to UNIX command cross reference, and a VMS to UNIX command cross reference are also included.
This book is designed for a broad range of users. It is for beginners who wish to learn UNIX from scratch. It provides intermediate and advanced users a complete reference containing command examples that are useful and provide insight on how to become a UNIX master. Finally, it serves the classroom instructor as an instructionally designed UNIX textbook.
The UNIX System is a sophisticated set of computer programs. The UNIX kernel is the main operating system program. The remainder of the System is made up of many powerful commands. The User Commands are available to all UNIX users.
