I have one more doubt..
Iam running a sql select command inside shell script and redirecting its output to a file.

Net::DNS::Header(3) User Contributed Perl Documentation Net::DNS::Header(3)NAME
Net::DNS::Header - DNS packet header class
SYNOPSIS
"use Net::DNS::Header;"
DESCRIPTION
A "Net::DNS::Header" object represents the header portion of a DNS packet.
METHODS
new
$header = Net::DNS::Header->new;
"new" creates a header object appropriate for making a DNS query.
parse
($header, $offset) = Net::DNS::Header->parse($data);
Parses the header record at the start of a DNS packet. The argument is a reference to the packet data.
Returns a Net::DNS::Header object and the offset of the next location in the packet.
Parsing is aborted if the header object cannot be created (e.g., corrupt or insufficient data).
print
$header->print;
Prints the header record on the standard output.
string
print $header->string;
Returns a string representation of the header object.
id
print "query id = ", $header->id, "
";
$header->id(1234);
Gets or sets the query identification number.
qr
print "query response flag = ", $header->qr, "
";
$header->qr(0);
Gets or sets the query response flag.
opcode
print "query opcode = ", $header->opcode, "
";
$header->opcode("UPDATE");
Gets or sets the query opcode (the purpose of the query).
aa
print "answer is ", $header->aa ? "" : "non-", "authoritative
";
$header->aa(0);
Gets or sets the authoritative answer flag.
tc
print "packet is ", $header->tc ? "" : "not ", "truncated
";
$header->tc(0);
Gets or sets the truncated packet flag.
rd
print "recursion was ", $header->rd ? "" : "not ", "desired
";
$header->rd(0);
Gets or sets the recursion desired flag.
cd

";
$header->cd(0);
Gets or sets the checking disabled flag.

";
$header->ra(0);
Gets or sets the recursion available flag.
ad
print "The result has ", $header->ad ? "" : "not", "been verified
"
Relevant in DNSSEC context.
(The AD bit is only set on answers where signatures have been cryptographically verified or the server is authoritative for the data and is
allowed to set the bit by policy.)
rcode
print "query response code = ", $header->rcode, "
";
$header->rcode("SERVFAIL");
Gets or sets the query response code (the status of the query).
qdcount, zocount
print "# of question records: ", $header->qdcount, "
";
$header->qdcount(2);
Gets or sets the number of records in the question section of the packet. In dynamic update packets, this field is known as "zocount" and
refers to the number of RRs in the zone section.
ancount, prcount
print "# of answer records: ", $header->ancount, "
";
$header->ancount(5);
