Word count

Script that lists all words used in one or more files and displays their count (pattern /\W+/ to split the lines of the input file into words can b used)..
It should display list in format word:count...gets Filename as an cmd line argument!
eg: $perl test doc (where doc is d file we are going to use)
is:200
and:50

why i should reinvent the wheel ?!

 45 sub wc
 46 {
 47 	my ($fname)=@_;
 48 	my $lines=0;
 49 	my $words=0;
 50 	my $chars=0;
 51 
 52 	open(FILE, $fname) || die "Couldn\'t open file $fname";
 53 	foreach my $line (<FILE>) {
 54 
 55 		$chars+=length($line);
 56 		$line=~/\n$/ and ++$lines;
 57 
 58 
 59 		$line=~s/^[ \t]*//g;
 60 		$line=~s/[ \t\r\n]*$//g;
 61 		my @w=split(/[ \t]+/, $line);
 62 		$words+=@w;
 63 	}
 64 
 65 	close(FILE);
 66 
 67 	return ($lines, $words, $chars);
 68 }
