UNIX time-sharing system: UNIX programmer's manual

This is volume 1 of a 2-volume set from Bell Labs. Back in the day, before the Internet and Linux, this was the best source for information on Unix. It consists of 425 pages in 8-1/2"x11" format with a comprehensive index. There are nine major sections: 1. Commands (183 pages) 2. System Calls (58 p.) 3. Subroutines (60 p.) 4. SPecial Files (22 p.) 5. File Formats and Conventions (26 p.) 6. Games (18 p.) 7. Macro packageas and language conventions (14 p.) 8. Maintenance (18 p.) 9. Quick Unix Reference (8p.) The bulk of the book, the Commands section, consists of what you can find using the "man" command nowadays. ( on line review)
