Students Guide to Unix

Harley Hahn0-07-025511-3

A practical guide to UNIX, this book is both a reference and a teacher. It explains things as they really are and recognizes that people like to play games, read news, send mail and copy remote files. It is broken down clearly for fast referencing and indexing with each chapter designed to be read as a single part which stands alone.
