array of structures

zedd386zedd386
in Perl
I'm getting input from the `last` command, putting it into @lastfile and parsing it up into these bits of info for each user on our system:

username
real name
# of logins
total time
average time

I've built an array that looks like:

$USER[$i]->{username} = "jbarker";
$USER[$i]->{realname} = "Jim Barker";
$USER[$i]->{logins} = 25;
$USER[$i]->{totaltime} = "3:15:25";
$USER[$i]->{average} = 125; #this is minutes


So the i'th element represents a user. What I need to know is this: Is there any reasonably easy way to sort this array? For example, what if I want to sort the array by average time, or by total time, or by username? Thanks for any help.

    hi

    you could check the function sort of perl
    you can sort by keys or by values
    :)
