Publisher's Synopsis
Several large companies such as Digital Equipment Corporation, Hewlett-Packard, Unisys and IBM are already implementing POSIX. This book is a tutorial-style introduction of POSIX.2, the shell programming language, and the POSIX.1 system interface. Professional in tone, this book is geared for programmers who currently work on proprietary operating systems which have introduced POSIX interfaces. For those programmers, this book shows the sufficient differences between UNIX and POSIX. Traditional UNIX programmers who want to know where the differences lie between UNIX and POSIX, should also appreciate this book.
