I have two perl files which after processing produce a output file. these files contain records, end part of which look like below.

 \"version\":\"2.0\"}")]]]

Now for few days we are receiving new line character in the records like below which is causing failure.

 \"version\":\"2.0\"}\n")]]]

Now for this I used the below extra statemnet (4th one in below code) which is working perfectly 

 
while(<AH>) {
  chomp;
  my $line=$_;
$line =~ s/\\n\"\)]]]$/")]]]/g;

[download]

Now problem is, that these files contain millions of records & because of this extra command it is taking exactly double time (earlier 1.5 hrs now 3 hrs). Is there any other way to remove it in efficient way...Please help.
