Hi ahamed101,

Below just few case of different input :
Input file 1
Code:
-       45472   46630
+       46817   47600
-       48573   49767

Desired Output file 1
Code:
-       45472   46630
+       46817   47600
+       46817   47600
-       48573   49767

Input file 2
Code:
+       81446   82784
-       82843   83058
+       89725   90700

Desired Output file 2
Code:
+       81446   82784
-       82843   83058
-       82843   83058
+       89725   90700

Basically I just wanna duplicate previous record if it shown as "- + -" or "+ - +" becomes "- + + -" or "+ - - +"

Sorry for confusing you Smilie

INTERFACE-ORDER(5)						    resolvconf							INTERFACE-ORDER(5)

NAME
interface-order - resolvconf configuration file DESCRIPTION
The file /etc/resolvconf/interface-order is used to control the order in which resolvconf nameserver information records are processed by those resolvconf update scripts that consult this file. (The name of the file is apt because a resolvconf nameserver information record is named after the interface with which it is associated.) The file contains a sequence of shell glob patterns, one per line. The position of a record in the order is the point at which its name first matches a pattern. Patterns may not contain whitespace, slashes or initial dots or tildes. Blank lines and lines beginning with a '#' are ignored. Resolvconf update scripts in /etc/resolvconf/update.d/ that consult this file include the current default versions of dnsmasq, pdnsd and libc. (Actually they don't read the file directly; they call the utility program /lib/resolvconf/list-records which lists records in the specified order and omits the names of empty records.) EXAMPLE
# /etc/resolvconf/interface-order # Use nameservers on the loopback interface first. lo* # Next use records for Ethernet interfaces eth* # Next use records for Wi-Fi interfaces wlan* # Next use records for PPP interfaces ppp* # Last use other interfaces * AUTHOR
