Acknowledgments

Thanks again to Yosef Gold for sharing his office with me. Deb Cameron again revised Chapter 8. Thanks to Mike Loukides at O'Reilly Media for his work as editor. Chuck Toporek, also of O'Reilly Media, answered numerous Mac OS X and Macintosh-related questions, for which I'm grateful. J.D. "Illiad" Frazer of User Friendly (see http://www.userfriendly.org/) provided the great cartoon on the back cover. It's a relief to finally know the tarsier's name.

Thanks to Jennifer Vesperman for permission to adapt material from Essential CVS for Chapter 14. Similarly, Ben Collins-Sussman, Brian W. Fitzpatrick, and C. Michael Pilato gave permission for me to adapt material from Version Control with Subversion for Chapter 15, which I greatly appreciate. And thanks to Andy Oram, Ellen Siever, Stephen Figgins and Aaron Weber for making available material from Linux in a Nutshell for use in parts of the book.

Thanks to David G. Korn (AT&T Research) and Chet Ramey (Case Western Reserve University) for answering my questions about the Korn shell and Bash. Keith Bostic of Sleepycat Software answered several questions about Berkeley DB. Glenn Barry of Sun Microsystems helped out on the Solaris side.

Thanks to the following people, in alphabetical order, for reviewing the book during its various stages: Nelson H.F. Beebe (University of Utah Mathematics Department), Jon Forrest (University of California, Berkeley, Civil and Environmental Engineering), and Brian Kernighan (Princeton University Computer Science Department). Chet Ramey, co-author and maintainer of Bash, reviewed Chapter 4, and Bram Moolenaar, the author of vim, reviewed Chapter 9, for which I thank them.

A special thanks to Dr. Uri Degen, Lev Orpaz, Julio Kadichevski, and Sid Gordon of Ness Technologies, and to Mike Hendrickson and Mike Loukides of O'Reilly Media, for enabling me to finish this edition in a timely fashion.

Once again, thanks to my wife Miriam for her love, patience, and support, and to my children for not giving Mommy (too much) hassle while I was working.
