NAME perl - Practical Extraction and Report Language SYNOPSIS perl [options] filename args DESCRIPTION Perl is an interpreted language optimized for scanning arbi- trary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks. The language is intended to be practical (easy to use, effi- cient, complete) rather than beautiful (tiny, elegant, minimal). It combines (in the author's opinion, anyway) some of the best features of C, sed, awk, and sh, so people familiar with those languages should have little difficulty with it. (Language historians will also note some vestiges of csh, Pascal, and even BASIC-PLUS.) Expression syntax corresponds quite closely to C expression syntax. Unlike most Unix utilities, perl does not arbitrarily limit the size of your data--if you've got the memory, perl can slurp in your whole file as a single string. Recursion is of unlimited depth. And the hash tables used by associative arrays grow as necessary to prevent degraded performance. Perl uses sophisticated pattern matching techniques to scan large amounts of data very quickly. Although optimized for scanning text, perl can also deal with binary data, and can make dbm files look like associative arrays (where dbm is available). Setuid perl scripts are safer than C programs through a dataflow tracing mechanism which prevents many stupid security holes. If you have a problem that would ordinarily use sed or awk or sh, but it exceeds their capa- bilities or must run a little faster, and you don't want to write the silly thing in C, then perl may be for you. There are also translators to turn your sed and awk scripts into perl scripts. [Librarian's Note: This version of PERL was ported to VMS. The buildfile to do it "right" needs MMS which your librarian lacks. Therefore all C programs were compiled and linked. There were warnings, but the perl.exe is here and may work. PERL.ZIP is the compressed, total PERL package including documents. The config.h and malloc.c had minor mods to get them to compile on my machine. - Glenn Everhart (Everhart@Raxco.com) ] The porting work was done by: Ben Armstrong, Software Development bus: (902)422-1973 Dymaxion Research Ltd., fax: (902)421-1267 Halifax, Nova Scotia, Canada B3J 1R2 Internet: bg@dymaxion.ns.ca PERL Practical Extraction and Report Language, VMS port 3.0.1 Abstract: Unavailable C Source: SEND PERL.PACKAGE (66 parts) 25-SEP-1992 Binary: Unavailable VMSSERV @ {OAK,ELM,ASH}.CC.KCL.AC.UK - INTERNET
