Chris F. A. Johnson was introduced to Unix in 1990 and learned shell scripting because there was no C compiler on the system. His first major project was a menu-driven, user-extensible database system with report generator. Chris uses the shell as his primary, general-purpose programming language, and his projects have included a member database, menuing system, and POP3 mail filtering and retrieval. Chris is the coauthor of Pro Bash Programming (Apress, 2015). When not pushing shell scripting to the limit, he designs and codes web sites, teaches chess, and composes cryptic crosswords.
