Unique items in a text file

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi There;
How can generate a html report from this text file to show all the unique items on the file? I could use split, but after that I am getting lost trying to count the unique item, like:
I would like to show something like,

Companies: 11<br>
FA: 2 <br>
DI: 2 <br>
DX:1 <br>
Login: 2 <br>
[download]

Thanks for the help!

Use a hash, something like the following code my %erg = (); while(<DATA>) { my @row = split(/,/,$_); ++$erg{$row[3]}; } print $_ . ': ' . $erg{$_} . '<br />' . "\n" foreach (keys %erg); __DATA__ Auto,00883,pw00,DX,4/15/2004,10:12:59,1110046,1 Auto,00883,pw00,FA,4/15/2004,10:15:45,, Magic,006513,pw13,Login,4/15/2004,10:16:23,, Car Wash,006513,pw3h,Not Found,4/15/2004,10:16:57,1232246, Home and Auto,006513,pw6513,DI,4/15/2004,10:17:09,15134346,1 Auto,00883,pw00,FA,4/15/2004,10:17:17,, Home,006513,pw6513,Login,4/15/2004,10:17:38,, Home,006513,pw6513,DI,4/15/2004,10:17:44,151234326,1 Deal Time,006513,pw001,Login,4/15/2004,10:53:31,1, Car Wash,006513,pw3h,DI,4/15/2004,10:53:46,11238748,1 Magic,006513,pw13,Login,4/15/2004,11:01:25,0, [download] Edit: fixed missing right-curly.

Hi, I run the code and it is printing back the total for all the item just like the problem I was having before, but thanks for your effort. Result prints: `48`	[reply] [d/l]

I got the same here, how would you do if you had to add this numbers up instead of displaying them in order?	[reply]

`perldoc -q duplicate` If the information in this post is inaccurate, or just plain wrong, don't just downvote - please post explaining what's wrong. That way everyone learns.	[reply] [d/l]
