I need to get a count of how many unique data values I have in my text file.
The text file has data like this:
123 56
123 56
234 45
123 56
678 93
678 93
I need the results of my script to look like this:
234 45 1
123 56 3
678 93 2
Here is my attempt and its not printing any data:
my $file = 'filehere.txt';
open(DATA, "$file") || die "Can not open: $!\n";
my @array = (<DATA>);
close(DATA);
open(DATA, "$file") || die "can t open: $!\n";
my %hash = ();
foreach $item (@array)
{
$hash{$item}++;
}
print "$item\t$hash{$item}\n";
close(DATA);

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
