Thanks a ton duyet.. You are a life saver :) One final question pls. The log file has been updated with a new entry called Files, like below for example 
JIRA: COM-6789
Program:Testing
Reviewer:Chan Joe
Description:SO hwat 
rev:r698392
Files: dev/src/com/user/st/recall/api/API.java

Since 'Files' may have multiple file entries separated by a newline like above, I'm facing the below message 
  Files => base/dev/src/com/myorg/ng/order/util/Util.jsp;base/dev/src/
+com/myorg/ng/sterling/sth/api/Update.jsp
    Description => My design initiative .

    The code in the else block within the while loop should be changed: 
            # store data in a temp hash
        if ( $line =~ m/:/ )
        {
            my ( $key, $value ) = split /:\s*/, $line;
            $hash->{ $key } = $value;
        }
        elsif ( $line =~ m#/# && exists $hash->{Files} )
        {
            $hash->{Files} .= ";$line";
        }

          Below is the modified section in the code: 
             my $program = $hash->{Program} || '';
        my $jira    = $hash->{JIRA}    || '';
        my $qa    = $hash->{QA}    || '';
        my $dev    = $hash->{DEV}    || '';
        if ( $program && $jira ) 
        {
            push @{ $data->{ $program }{ $jira }}, $hash;
            $hash = {};
        }
        elsif ( $program && $qa) 
        {
            push @{ $data->{ $program }{ $qa}}, $hash;
            $hash = {};
        }
        elsif ( $program && $dev) 
        {
            push @{ $data->{ $program }{ $dev}}, $hash;
            $hash = {};
        }
    }
    else
    ...
    ....
