Thanks for the quick reply. Your code works as you described and as I requested, but I don't think I explained what I needed very well. Your code creates each series as an element in the array (each line of data is an element), but I need to be able to separate out the PID data in order to work with it. I need the user to log what user was involved, and I need the time to be able to sort the list and choose the 10 "oldest" PIDS for the day. To illustrate, here's the same data:

user1 machine1 (v1.1) (flexlmserver/27000 1009), start Sat + 3/30 12:53 user2 machine2 (v1.1) (flexlmserver/27000 123), start Sat +3/30 2:45

With your code gives me the output:

$parsed[0] = user1,1009,12:53 $parsed[1] = user2,123,2:45

When I need something like:

@row1 = (user1,1009,12:53) $row1[0] = user1 $row1[1] = 1009 $row1[2] = 12:53 @row2 = (user2,123,2:45) $row2[0] = user2 $row2[1] = 123 $row2[2] = 2:45

So perhaps what I really need is a multidimensional array or a way to split up the file into a grid? My end goal is to take the oldest PIDs so I can run a command on those PID numbers. Therefore I need to associate the time with the PIDs so I can identify the ones I need. You are correct the I am not asking for the correct data construct. Any further suggestions would be greatly appreciated.

    Just push the array ref instead of a string, then you can sort.
    while ( <DATA> ) { my @wanted = ( split )[ 0, 5, 9 ]; $wanted[1] =~ s/\D//g; $wanted[2] = sprintf "%05s",$wanted[2]; push @parsed, \@wanted; } print "@$_\n" for sort { $a->[2] cmp $b->[2] } @parsed;

      Excellent, POJ. This works well. I need to piece through your code to understand exactly what is doing, but I wondered if you could expand on this approach to help me in my next step. I need to identify the ten oldest PIDS and then them through another command. For simplicity, I'll just select the 2 oldest for this example. Once I identify those PIDS, I need to run the command:

      lmutil lmremove -h $PRODUCT $flexlmserver 27000 $PID[x]

      Where $PIDx would be the two oldest (or whatever # I want to select) PIDS. I'm sure this can be done using your approach, but I have no idea of the syntax. Thanks so much for your time.

        This simple example assumes you don't want to capture the output of the command or check for success
        while ( <DATA> ) { my @wanted = ( split )[ 0, 5, 9 ]; $wanted[1] =~ s/\D//g; $wanted[2] = sprintf "%05s",$wanted[2]; push @parsed, \@wanted; } my @sorted_by_time = sort { $a->[2] cmp $b->[2] } @parsed; # oldest my $LIMIT = 2; my $count = 0; for (@sorted_by_time){ my $PID = $_->[1]; system("lmutil lmremove -h $PRODUCT $flexlmserver 27000 $PID"); last if ++$count >= $LIMIT }
