This is the authoritative guide to the hottest new UNIX utility in years, coauthored by its creator, Larry Wall. Perl is a language for easily manipulating text, files, and processes. Perl provides a more concise and readable way to do many jobs that were formerly accomplished (with difficulty) by programming in the C language or one of the shells. Even though Perl is not yet a standard part of UNIX, it is likely to be available wherever you choose to work. And if it isn't, you can get it and install it easily and free of charge.
Contents include:
An introduction to Perl
Common tasks with Perl
Real Perl programs; includes database manipulation, programming aids, system administration, text and filename manipulation, interprocess communication, and more
Perl syntax
Perl functions
Other oddments; invocation options, debugging, efficiency, the Perl library, linking in C subroutines, etc.
Also includes a pull-out quick-reference card (designed and created by Johan Vromans).
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal featured on the cover of Programming perl is a camel, a one-humped dromedary. A hoofed mammal, relative of the llama and alpaca, camels first appeared 38 million years ago and once populated all large land masses but Australia. For some unknown reason, they died off in all but the Middle East, Central Asia, India, and North Africa, and now only two species remain, the one-humped dromedary and the two-humped bactrian. The dromedary is the larger and stronger of the two, standing seven feet tall at the top of its hump and able to carry an average load of 400 pounds. With only the weight of one rider, a dromedary can move at ten mph all day. Loaded down in caravan, they will move 30 miles per day. UNIX and its attendant programs can be unruly beasts. Nutshell Handbooks(R) help you tame them.

Edie Freedman designed this cover and the entire UNIX bestiary that appears on other Nutshell Handbooks. The beasts themselves are adapted from 19th-century engravings from the Dover Pictorial Archive.
