From the Back Cover
The third edition of Unix System V: A Practical Guide is a complete tutorial guide to System V Release 4.2 that has been thoroughly updated to reflect the changes made in this version of Unix.
With a look and feel almost identical to that of Unix, Coherent is a virtual clone of the Unix operating system for the PC. Users will gain practical, hands-on experience from this mini-version of the Coherent operating system, taking advantage of Coherent's multi-user, multi-tasking capabilities and utilizing a wide range of utilities and commands. To make this software even easier to use, online help is included and the commands discussed both in the book and on the diskette have the same name and function.
Essentials of Coherent includes:
- The shells: ksh and sh
- Commands for displaying and manipulating files: awk, cat, cp, ed, find, grep, head, kill, lc, ls, ln, me, mkdir, mv, pg, qfind, rm, rmdir, sed, sort, tail, uniq, vi, and wc

The 3.5" and 5.25" diskettes will run on IBM PC-AT (and compatible) 286, 386 and 486 machines. At least 640K of RAM is required. The software will only function through the A floppy drive. It will not function through the B drive or on microchannel-based machines.
