Are there any good introductory tutorials for Perl server-side scripting available freely on the internet?
I checked perl.org and google searches like perl server scripting, server side script examples in perl, but did not get any good results.
Is Perl not that common as a server-side language? It is mentioned here as one.
The classic book by the author of the classic CGI.pm module. A bit old, but the concepts haven't changed all that much. Certainly a good place to start:
Perl is an excellent scripting language. It is used mostly for 'server' stuff. So only material which is not about server side programming will mention its purpose more clearly.
Also when you say server scripting, you might want to be a bit more specific as to what you are looking for ... system administration ? Web applications ? ...
I find that I learn best when I have a concrete task at hand, so instead of looking for server programming, look for something more specific.
If you mean server-side scripting for websites, this looks This looks pretty good: Perl & CGI tutorial, or the CGI section of this PDF or on TutorialIndex. You could ask on PerlBuzz.
But my top recommendation would be to get MySQL and Perl for the Web by Paul DuBois - I think it's one of the best and most focussed books on the entire subject. Finally, and (for a nice lightweight web solution) you could also take a look at the CGI::Application-based Titanium web framework.
But Perl's a good general-purpose language anyway, and (according to this O'Reilly video from their Perl courses) there are more Perl jobs than programmers...
