This page includes many shell, Perl and SQL scripting tutorials. Here is my unix backup tutorial  with some example shell scripts. Find here
all programming tutorials. Assembly, C, C++, HTML, Perl etc. etc.....
This Tutorial assumes that the reader knows nothing of
programming whatsoever, but needs a solid grounding for further work. After you
finish this course you'll be ready to specialise in CGI, sysadmin or whatever you
want to do with Perl.
PERL- The Perl Journal TPJ is the only magazine devoted to Perl, featuring in-depth articles from Perl experts.
