10.6 References and Further Study

The Bourne shell is well documented in the sh man page. There are many extensive references on the Perl language, both in books and on-line. The web site http://www.perldoc.com/ is a good, canonical source for on-line documentation and also contains links to other sites with information on Perl. There is so much information in the online Perl manuals that the man page has been split into many different man pages. Typing man perl will list an index of the other perl man pages. Particularly useful are perlsyn for Perl syntax, perlfunc for information about Perl functions, perlop for information about Perl operators and perlre for information about Perl regular expressions. The books Programming Perl , 3rd ed., (O'Reilly and Associates, 2000) by Larry Wall, Tom Christiansen, and Jon Orwant and Learning Perl , 3rd ed., (O'Reilly and Associates, 2001) by Randal L. Schwartz and Tom Phoenix are commonly used references for Perl.
