Keep it on your desk as you write scripts, and you'll be able to quickly find the particular option you need.

Author Biography

Paul Raines is a physicist and scientific programmer at the Stanford Linear Accelerator Center at Stanford University where he is part of a large collaboration studying CP violation (why charge and parity are not conserved in some particle decays). He is a huge advocate of scripting languages and has been using Tcl on various projects since 1992. He is also the coauthor of O'Reilly & Associates' Tcl/Tk in a Nutshell. When he can get away from the lab, Paul enjoys hiking, bridge, and soccer.

When Jeff Tranter was first exposed to UNIX-based workstations about ten years ago, he dreamed of being able to afford a system with similar capabilities for home use. Today, he sees Linux as the realization of that dream, with the added bonus of being able to examine and modify all of the source code and even contribute to its development. He's been using Linux since 1992 and is the author of the freely available Linux Sound and CD-ROM HOWTO guides. Jeff has also written a number of Linux utilities and several Linux related magazine articles. Jeff received his bachelor's degree in electrical engineering from the University of Western Ontario. He currently works as a software designer for a high-tech telecommunications company in Kanata, Ontario, Canada's Silicon Valley North.
