To get the statistics you want, it may be easier to slurp the whole file into a variable then process it through a series of regexes. Here's the basic idea, but as suaveant suggests - read up on regular expressions: 

open (READFILE, $filename)|| die "Failed to open $filename: $!";
my $filecontents;
{
    local undef $/;
    $filecontents = <READFILE>;
}
close <READFILE>;

my @words = $filecontents =~ / ... /g;
my $wordcount = scalar @words;

my @characters = ...

my @sentences = ...

# etc

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
