About the Author
Chris F. A. Johnson was introduced to Unix in 1990 and learned shell scripting because the system he was using had no C compiler. His first major project was a menu-driven, user-extensible database system with a report generator. Chris's recent shell projects have included a member database, menuing system, and POP3 mail filtering and retrieval. When not pushing shell scripting to the limit, Chris teaches chess and composes cryptic crosswords.
