Hi.

With the data on file z1, the command:
Code:
pcregrep -o1 '=(.*)' z1

produces:
Code:
IN32

On a system like:
Code:
OS, ker|rel, machine: Linux, 3.16.0-7-amd64, x86_64
Distribution        : Debian 8.11 (jessie) 
csh - ( /bin/csh, 2016-02-04 )

And more details on pcregrep:
Code:
pcregrep        a grep with Perl-compatible regular expressions. (man)
Path    : /usr/bin/pcregrep
Version : 8.35
Type    : ELF 64-bit LSB shared object, x86-64, version 1 ( ...)
Help    : probably available with -h,--help
Repo    : Debian 8.11 (jessie)

This really has nothing to do with csh, but I ran it under csh to make sure it worked in this instance.

Best wishes ... cheers, drl

Net::DNS::Text(3)					User Contributed Perl Documentation					 Net::DNS::Text(3)

NAME
Net::DNS::Text - Domain Name System text representation SYNOPSIS
use Net::DNS::Text; $object = new Net::DNS::Text('example'); $string = $object->string; $object = decode Net::DNS::Text( $data, $offset ); ( $object, $next ) = decode Net::DNS::Text( $data, $offset ); $data = $object->encode; $text = $object->value; DESCRIPTION
The "Net::DNS::Text" module implements a class of text objects with associated class and instance methods. Each text object instance has a fixed identity throughout its lifetime. METHODS
new $object = new Net::DNS::Text('example'); Creates a text object which encapsulates a single character string component of a resource record. Arbitrary single-byte characters can be represented by followed by exactly three decimal digits. Such characters are devoid of any special meaning. A character preceded by represents itself, without any special interpretation. decode $object = decode Net::DNS::Text( $buffer, $offset ); ( $object, $next ) = decode Net::DNS::Text( $buffer, $offset ); Creates a text object which represents the decoded 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 offset of the text data. The returned offset value indicates the start of the next item in the data buffer. encode $data = $object->encode; Returns the wire-format encoded representation of the text object suitable for inclusion in a DNS packet buffer. value $value = $text->value; Character string representation of the text object. string $string = $text->string; Conditionally quoted zone file representation of the text object. BUGS
Coding strategy is intended to avoid creating unnecessary argument lists and stack frames. This improves efficiency at the expense of code readability. Platform specific character coding features are conditionally compiled into the code. COPYRIGHT
