Understood... thank you! In steps 4,5,6 I am having syntax issues. Is the sorted array on the right? @unsotrted = sort {$b <=> $a } @sorted;
Here is my code:
#use diagnostics;
use warnings;
use strict;
my $file = qq(/var/adm/sa/vm);
my $vmout = qq(/var/adm/sa/vm.out);
my $cpuout = qq(/var/adm/sa/cpu.out);
my $art = qq(/var/adm/sa/arout);
my @ar = ();
my @ar2 = ();
open (FILE, "<$file") || die "unable to open file $!";
open (MEMOUT, ">>$vmout") || die "unable to open file $!";
open (CPOUT, ">>$cpuout") || die "unable to open file $!";
while (<FILE>) {
local $, = "\n";
s/id//, s/wa//, print CPOUT push @ar, +(split)[16], $,;
s/id//, s/wa//, print MEMOUT +(split)[4], $,;
}
close (MEMOUT) or warn "unable to close file $!";
close (CPOUT) or warn "unable to close file $!";
close (FILE) or warn "unable to close file $!";
@ar = sort { $a <=> $b } @ar;
print "Now printing array 1\n", @ar;

- Why are you separating statements with commas instead of semi-colons?
- Are you sure you want to remove 'id' and 'wa' once before the first print, and a second time for the second print?
- Why are you pushing $, on the array?
- Are you sure you want to print even numbers to '/var/adm/sa/cpu.out'?
- What's with the local $,, and then putting it in a list you're printing to a file?
- What's the purpose of @ar2?
- What happened when you tried?
- What does the manual page say about sort, and where the unsorted list is?
- Do you know any other function where the argument is on the LHS of the assignment, and where the result is put into its last argument?
- Why are you using bareword filehandles instead of lexical variables?
