Hi,

I am getting different result from accessing an array as oppose to reading from a file.

Earlier I was executing a unix command and reading the result like this: 

system("lpstat -v -d -p -l -D >junk.txt");
open RI,"<junk.txt" || die "Can't open junk.txt for reading:$!\n";

my $data = do { local $/; <RI> }; # or however you load it.

my( %device, %system );

for ( split /\n(?=\S)/, $data )
{
  if( /^device for (.*?):.*?\1$/  )
  {
  
      $device{$1} = $1;
  }
  elsif ( /^system for (.*?): (\S+)/ )
  {
    $system{$1} = $2;
  }

But now I want to avoid opening and reading from a file so I use an array instead:

my @output =`lpstat -o -v -d -p -l -D`;.
my( %device, %system );
foreach my $line (@output) {
    chomp $line;

for ( split /\n(?=\S)/, $line )
{
  if  (/^system default/)
   {
     @test = split(/ /);
     chomp($test[3]);
     print "$test[3]|\n";
   } 
  if( /^device for (.*?):.*?\1$/  )
  {
  
      $device{$1} = $1;
  }
  elsif ( /^system for (.*?): (\S+)/ )
  {
    $system{$1} = $2;
  }

But by using an array I am getting a different answer than what I am getting by using a file.

How can I change my "array" code so that it works just like reading a file.
