Since both of us work for Sun Microsystems, this book is based on Sun's Solaris 1 and Solaris 2 operating environments. Solaris 1 is based on the implementation of UNIX known as BSD, which was done by the University of California at Berkeley (aka UCB). Solaris 2 is based on AT&T's SVR4 (System V Release 4) implementation. Both of the Solaris operating environments contain much more than just different flavors of the UNIX operating system. They also include OpenWindows and many other useful tools. Even though Solaris is our working base, we both have experience with other flavors of UNIX, and we know that our audience is also working with a wide mix of UNIX, XENIX , and other UNIX-like operating systems. So, with that in mind, as well as our limitations about not disclosing source, we endeavor to keep this book as generalized as possible while guiding you toward the goal of problem resolution. |
