Daniel Gilly joined O'Reilly Media, Inc a year after his graduation from MIT. As a staff writer, Daniel authored the 2nd Edition of Unix in a Nutshell, doubling its contents and paving the way for it to become one of O'Reilly Media's best-selling Unix titles. He revised Learning the vi Editor, co-wrote X Window System in a Nutshell, and had an editorial hand in several other books in the X Window series.

Daniel left O'Reilly after 6 years to pursue technical writing in Silicon Valley. He had a successful career with a wide range of tech companies -- from start-ups to mid-sized companies to one-time tech titans like Netscape and Sun Microsystems -- culminating with 5 years at Google.

In 2010, Daniel retired from Silicon Valley life and moved to Palm Springs, California to enjoy the sunshine and relaxed pace of this desert oasis.

You may have seen UNIX quick-reference guides, but you've never seen anything like UNIX in a Nutshell. Not a scaled-down quick reference of common commands, UNIX in a Nutshell is a complete reference containing all commands and options, along with generous descriptions and examples that put the commands in context. For all but the thorniest UNIX problems, this one reference should be all the documentation you need.

The second edition of UNIX in a Nutshell starts with thorough coverage of System V Release 3. To that, we've added the many new commands that were added to Release 4 and additional commands that were added to Solaris 2.0.
