Hello,
Awk seem treat the pattern as regular expression, how can awk search not using regular expression? e.g. just represent for "", not "A" or "a" . I don't want to add backslash . (2 Replies)

Hi, I need your help. I've got two files and i need to add 2nd line after occurrence of "Group No X" from data2.txt to 3rd line (after occurrence of "Group No X") from data1.txt. There is the same number of "Groups" in both files and the numbers of groups have the same pattern.

I am trying to do some math, so that I can compare the average of six numbers to a variable.
Here is what it looks like (note that when I divide really big numbers, it isn't a real number):

Anyone ever seen this? Someone mentioned this the other day....
If you do, for instance, in korn shell, echo $(5.2+2.5), it gives the result of 6 regardless.
Can't remember why but it was the limitation of the korn shell. (5 Replies)
Hi expert,

net::dns::domainname
Net::DNS::DomainName(3) User Contributed Perl Documentation Net::DNS::DomainName(3)NAME
Net::DNS::DomainName - DNS domain name wire representation
SYNOPSIS
use Net::DNS::DomainName;
$object = new Net::DNS::DomainName('example.com');
$name = $object->name;
$data = $object->encode;
( $object, $next ) = decode Net::DNS::DomainName( $data, $offset );
DESCRIPTION
The Net::DNS::DomainName module implements the concrete representation of DNS domain names used within DNS packets.
Net::DNS::DomainName defines methods for encoding and decoding wire format octet strings as defined in RFC1035. All other behaviour,
including the new() constructor, is inherited from Net::DNS::Domain.
The Net::DNS::DomainName1035 and Net::DNS::DomainName2535 packages implement disjoint domain name subtypes which provide the name
compression and canonicalisation specified by RFC1035 and RFC2535. These are necessary to meet the backward compatibility requirements
introduced by RFC3597.
METHODS
new
$object = new Net::DNS::DomainName('example.com');
Creates a domain name object which identifies the domain specified by the character string argument.
decode
$object = decode Net::DNS::DomainName( $buffer, $offset, $hash );
( $object, $next ) = decode Net::DNS::DomainName( $buffer, $offset, $hash );
Creates a domain name object which represents the DNS domain name identified by the wire-format data at the indicated offset within the
data buffer.
The argument list consists of a reference to a scalar containing the wire-format data and specified offset. The optional reference to a
hash table provides improved efficiency of decoding compressed names by exploiting already cached compression pointers.
The returned offset value indicates the start of the next item in the data buffer.
encode
$data = $object->encode;
Returns the wire-format representation of the domain name suitable for inclusion in a DNS packet buffer.
Net::DNS::DomainName1035
Net::DNS::DomainName1035 implements a subclass of domain name objects which are to be encoded using the compressed wire format defined in
RFC1035.
use Net::DNS::DomainName;
$object = new Net::DNS::DomainName1035('compressible.example.com');
$data = $object->encode( $offset, $hash );
( $object, $next ) = decode Net::DNS::DomainName1035( $data, $offset );
Note that RFC3597 implies that the RR types defined in RFC1035 section 3.3 are the only types eligible for compression.
encode
$data = $object->encode( $offset, $hash );
Returns the wire-format representation of the domain name suitable for inclusion in a DNS packet buffer.
The optional arguments are the offset within the packet data where the domain name is to be stored and a reference to a hash table used to
index compressed names within the packet.
If the hash reference is undefined, encode() returns the lowercase uncompressed canonical representation defined in RFC2535(8.1).
Net::DNS::DomainName2535
Net::DNS::DomainName2535 implements a subclass of domain name objects which are to be encoded using uncompressed wire format.
Note that RFC3597, and latterly RFC4034, specifies that the lower case canonical encoding defined in RFC2535 is to be used for RR types
defined prior to RFC3597.
use Net::DNS::DomainName;
$object = new Net::DNS::DomainName2535('incompressible.example.com');
$data = $object->encode( $offset, $hash );
( $object, $next ) = decode Net::DNS::DomainName2535( $data, $offset );
encode
$data = $object->encode( $offset, $hash );
Returns the uncompressed wire-format representation of the domain name suitable for inclusion in a DNS packet buffer.
If the hash reference is undefined, encode() returns the lowercase canonical form defined in RFC2535(8.1).
