|PWB_UNIX_Edition_1_Section_1_May77.pdf||UNIX is a Trade/Service Mark of the Bell System.
This manual was set on a Graphic Systems, Inc.
phototypesetter driven' by the'TROFF formatting 'program
Qperating under the 'PWB/UNIX system. The text of the
manual was prepared using the Ef) rexteditor.
The form and organization of this manual, as well as a major fraction of its contents, have been
copied from the UNIX Programmer's Manual-Sixth Edition, by K. Thompson and D. M. Ritchie
(Bell Telephone Laboratories, May 1975). The number of our colleagues who have contributed
to UNIX and PWB/UNIX software and documentation is, by now, too large to list here, but the use-
fulness and acceptance of UNIX and of PWB/UNIX is a true measure of their collective success.
