Klappentext TECHNOLOGY BACKGROUNDPerl is a script programming language that is similar in syntax to the C language. When compiled! a Perl program is almost (but not quite) as fast as a fully precompiled C language program. Perl is regarded as a good choice for developing common gateway interface (CGI) programs because it has good text manipulation facilities (although it also handles binary files). In general! Perl is easier to learn and faster to code in than the more structured C and C++ languages. Perl programs can! however! be quite sophisticated.DESCRIPTIONMost Perl programmers have been frustrated at one time or another because the system just wouldn't do what they wanted it to. There was that one simple! and obvious utility that was missing that would make life so much easier: A tool to get a stock quote! show off a photograph collection! or even display a collection of favorite comics. This book is about writing those utilities quickly and easily. Perl is the ideal language for writing utilities because it frees the programmer from many of the details of programming and just lets them write something useful. Because Perl is so useful! it has become the language of choice for utility programmers.KEY SELLING POINTS- Capitalizes on the success of Wicked Cool Shell Scripts! 1593270127- Over one million Perl programmers- A collection of handy utilities that solve difficult problems- A great supplement to any best-selling Perl book- Targets the savvy Perl programmer! but explains all aspects of Perl Zusammenfassung You can do a lot strange and wonderful things with the Perl language - if you know how.
