About the author

Tom Ryder is a systems administrator living in New Zealand who works for an internet services provider. He loves terminals, text editors, network monitoring and security, Unix and GNU/Linux, shell script, and programming in general. He is also the author of the Nagios Core Administration Cookbook.

Thanks go to the Packt editors and reviewers; to Richard Stallman, Brian Fox, and Chet Ramey for the GNU Project and the Bourne-Again Shell; to the authors of Greg's Wiki and the Bash Hackers Wiki; to Cory Sadowski for many entertaining chats about shell script over the years; to my boss, James Watts, for contractual permission to write yet another book; and, of course, to the lovely Chantelle Potroz.
