Hello, i know that there is a way to remove whitespace

sub trim($)
{
    my $string = shift;
    $string =~ s/^\s+//;
    $string =~ s/\s+$//;
    return $string;
}

$str = "   Hello     ";
$str =~ trim($str);
print $str; #"Hello"

I need to do this exact same thing, except more vertical. I have this file:

This is a line.

:O and this is another line.


This line is a bit more of a loner, because hes 2 lines away.

And i would like it to look like this:

This is a line.
:O and this is another line.
This line is a bit more of a loner, because hes 2 lines away.

So, basically all it does, is reads the file and removes all blank lines. (some of these lines have spaces and indents on them, it should first clear those out :)) This is what i have so far:

opendir(DIR, ".");
for $file (glob("*.shtml"))
{
    $line = "";
    $file_data = "";
    open(FILE, $file);
    my @data = <FILE>;
    foreach my $line (@data)
    {
        #Work to be done on each line of the file

        $file_data .= $line; #rebuild file
    }
        open (WRITE_FILE, ">$file");
        print WRITE_FILE $file_data;
        close WRITE_FILE;
        close FILE;
        print "Processing... ".$file."... Done!\n";
}
close DIR;

Thanks a ton guys :) ~Cody Woolaver
