If i had a text file, how would i write a small script to reprint the file to the screen but removing all the new line characters and converting everything to lowercase???
so far i've learnt how to work out how many lines there are in the file... ie.
#!usr/local/bin/perl

use strict;

use warnings;



my %lineHash;

my @lineArray;

print ("Enter filename to count lines: ");

my $path=<STDIN>;

print ("\n");

open(DATA, "<$path") || die "Couldn't open $path for reading: $!\n";

while (<DATA>)

{

    while (s/(\n)(.*)/$2/)

    {

        my $count = $1;

        $lineHash{$count}++;

    }

}

close (DATA);

my %charname = ( "\n" => "Lines" );

while ( my ($lines, $count) = each(%lineHash) )

{    

    push @lineArray, "$count\t$lines";

    print ("$count\t$charname{$lines}\n");

}
