I am writing a script to parse log. I am reading each line from the log and if some condition satisfies I want store that line to some buffer variable and I want to use that buffer later. but the problem is when I print buffer later, the value is changed to the last line. here is the snippet. 
while (<$fhlog>)
{
my $line = $_;
my $bufferline;
if ($line =~ /Finished (.*)\. Wrote (\d+) new, (\d+) duplicates, (\d+)
+ archived/)
 {
  &storeAdapterDetails($1, $2, $3, $4, $fhresult);
  next;
 }
 if ($line =~ /ERROR/)
 {
  $bufferline = '$line';
  next;
 }
 if ($line =~ /.*Exception:/)
 {
  print "Found adapter: ".$bufferline;            
  $flag = 1;
 }
