Yes there are plenty of books and websites, varying in quality from
great to abysmal, but the best place to look for help is on your hard
disk. These is a whole heap of documentation that comes with Perl (in
HTML with Activestate Perl) that matches the version of Perl that you
have (unlike most books and websites), including tutorials. For example
see 'perldoc perlretut' for a tutorial on regular expressions, also
'perldoc perlrequick', and 'perldoc perlre' for a more detailed
reference. Also, given the apparent nievity of the original question, I
would suggest starting with 'perldoc perlintro'.
[Just a note, in case the OP is still watching, 'perldoc <something>' in
this context is a shorthand for either type 'perldoc <something>' at a
command line prompt, or look up <something> in the table of contents of
your HTML documentation.]
