Greg Lehey is an independent computer consultant specializing in UNIX. Born in Australia, he was educated in Malaysia and England before studying chemistry in Germany and chemical engineering in England. He has spent his professional career in Germany, where he worked for computer manufacturers such as Univac and Tandem, the German space research agency, nameless software houses, and a large user before deciding to work for himself. In the course of over 20 years in the industry he has performed most jobs you can think of, ranging from kernel support to product marketing, systems programming to operating, processing satellite data to programming gasoline pumps. About the only thing he… hasn't done is write commercial software. He is currently engaged in the production of CD-ROMs of ported free software, and this book is one result of his experience in this area. He is available for short-term contracts and can be reached by mail at grog@lemis.de.
