Here's a quick snippet that should suggest the type of structure that could work for the task:
my %hash;
while (my $line=<IN>) { # I assume an open IN filehandle
chomp $line;
($username, $realname, $pwd) = split /\t/, $line; # I assume tab del
+imiter
$hash{$username} = [$realname, $pwd];
}
Then you can access someuser's realname or password like:
$realname = $hash{'someuser'}->[0];
$pwd = $hash{'someuser'}->[1];
My recommendation would be to look at the references manpage for the background on how to build and work with simple data structures.
Good luck.
