search for string and replace backwards
I'm new to Unix scripting and I'm not sure if this can be done. Example:
search (grep) in a file for 'Control ID' and then replace with 4 blanks 7 bytes before 'Control ID.
input
"xxxxxx1234xxxxxxxControl IDxxxxxx"
output:
"xxxxxx xxxxxxxControl IDxxxxxx"
thanks!

net::ldap::control::relax
Net::LDAP::Control::Relax(3) User Contributed Perl Documentation Net::LDAP::Control::Relax(3)
NAME
Net::LDAP::Control::Relax - LDAPv3 Relax control object
SYNOPSIS
use Net::LDAP;
use Net::LDAP::Control::Relax;
$ldap = Net::LDAP->new( "ldap.mydomain.eg" );
$relax = Net::LDAP::Control::Relax->new();
$msg = $ldap->modify( 'dc=sub,dc=mydomain,dc=eg",
changes => [
replace => { modifyTimestamp => '19700101000000Z' } ],
control => [ $relax ] );
die "error: ",$msg->code(),": ",$msg->error() if ($msg->code());
DESCRIPTION
"Net::LDAP::Control::Relax" provides an interface for the creation and manipulation of objects that represent the "Relax" control as
described by draft-zeilenga-ldap-relax-03.txt
The presence of the Relax control in an LDAP update request indicates the server temporarily relax X.500 model constraints during
performance of the directory update.
The control is appropriate for all LDAP update requests, including add, delete, modify, and modifyDN (rename) [RFC4511].
Its criticality is always set to TRUE, and no value.
There is no corresponding response control.
CONSTRUCTOR ARGUMENTS
Since the "Relax" control does not have any values only the constructor arguments described in Net::LDAP::Control are supported
METHODS
As there are no additional values in the control only the methods in Net::LDAP::Control are available for "Net::LDAP::Control::Relax"
objects.
