Beskrivning

The bash shell is a complete programming language, notmerely a glue to combine external Linux commands. Bytaking full advantage of shell internals, shell programscan perform as snappily as utilities written in C orother compiled languages. And you will see how, withoutassuming Unix lore, you can write professional bash 4.0programs through standard programming techniques.

Mer om författaren

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 author of Shell Scripting Recipes: A Problem-Solution Approach (Apress, 2005). When not pushing shell scripting to the limit, he designs and codes web sites, teaches chess, and composes cryptic crosswords.
