This seemed easy to me last night and for some reason I can't get this to work on my head, or in script.

I have a log file that looks like 

Big Bird 10 20 40 50
Calvin Klein 45 30 100 80 10
Mother Natures 100 100 23

I need to open this log file, sort my last name alphabetically, and print everything out. Easy? I knew it was but my mind is playing tricks on me.

My original thought was to split it by spaces at first so I can get the two names, and all the numbers in one var since they're not important to have separate. Then create a new array to store the new results in an order I can sort. From there, just print it out.

The problem I am running into is the digits, I can't capture all of them no matter what I've tried.

Can someone help me find a solution and let me know why my solutions weren't working? 

open (LOG, $log) or die "Error: $!";
my @lines = <LOG>;
close(LOG) or die "Error: $!";

my @good_results;

foreach my $key (@lines)
{
  # my ($fname, $lname, $grades) = split(/\w+/, $key);

   my ($fname, $lname) = split(/ /, $key);
   $key =~ m/\w+\s+(\d+\s)$/;
   my $grades = $1;

   print "$lname and $fname $grades\n";

   #push(@good_results, "$lname $fname $grades");
}

#print join("\n", sort @good_results);
