UNIX

Introduction
When molecular modeling applications were first being developed 15 or so years ago, the only operating system available that could accommodate the demands of these applications was UNIX. Thus, most modeling programs that we will use in this course run under UNIX, though it should be recognized that many “flavors” of UNIX exist. These different varieties of UNIX include Linux and the Mac OS X. Many modeling applications also have been ported to Windows.

On-Line Reference
An excellent on-line resource, which includes tutorials and demonstrations of various commands, is the Unix Station.

A listing of “Most-Used UNIX Commands” is available.

Early development of UNIX was done at Bell Labs. Discussions of the history of the development as well as an overview of UNIX are available.

Printed References
Many books related to the UNIX operating system have been published. A good source of books on many different aspects of UNIX is O’Reilly & Associates, Inc. One book, which is distinguished by its conciseness is
