Greetings again all of you good monks.

I am attempting to set up a very simple Perl app using the 'who' command in Unix.

Basically I want to set up a simple hash using somthing like:

my %who=('who -q');
[download]

I would then like then like to set each of the returned usernames as keys for the hash and have the values in the hash show the number of sessions that a user is logged in.

The read out would look something like:

Beckysue is logged in 1 time.
Billybob is logged in 3 times.
BubbaJoe is logged in 2 times. 
Saranne  is logged in 1 time. 
<br><br>
ect...
[download]

I have a strong urge to try the functions keys(%hash) and values(%hash) but I think I also might be haveing problems passing data from that 'who' command.



Thank you in advanced, I am trying to learn Perl from my home in Beijing with very limited help in meatspace. I have been ramming my head into the desks for the last few hours and the this is upseting the little old lady nextdoor. If anyone can offer a hint, you would be my hero for the day (or night).
