Script to sort Cisco configs
Hi everyone Smilie,

I need sort Cisco configs to report but i cannot do the script to made this:

#### INPUT #####
Code:
 
config-register 0x2102
version 12.2
!
hostname Router
!
interface Ethernet0
description Red LAN
ip address 192.168.1.1 255.255.255.0
no cdp enable
!
interface Serial0
description Red WAN
ip address 172.16.1.1 255.255.255.0
!
interface loopback0
shutdown
!
line con 0
exec-timeout 20 0
stopbits 1
!
line vty 0 4
exec-timeout 20 0
transport preferred none
!
end

### OUTPUT ###
Code:
config-register 0x2102
version 12.2
hostname Router
interface Ethernet0 description Red LAN
interface Ethernet0 ip address 192.168.1.1 255.255.255.0
interface Ethernet0 no cdp enable
interface Serial0 description Red WAN
interface Serial0 ip address 172.16.1.1 255.255.255.0
interface loopback0 shutdown
line con 0 exec-timeout 20 0
line con 0 stopbits 1
line vty 0 4 exec-timeout 20 0
line vty 0 4 transport preferred none
end

Can someone help me with this?, I was trying with awk, grep, etc but I failed.

Thanks Smilie

Not perfect but should work
Code:
awk 'END{print}/!/{getline;x=$0;next}{if(NR<3){print;next}else{print x,$0}}' file

It works fine for the example, thanks a lot, but have an additional issue.

If the configuration has the following statements:

### INPUT ###
Code:
!
class-map match-all critical
 match ip dscp af31 
class-map match-all video
 match ip dscp ef 
!

### OUTPUT must be ###
Code:
class-map match-all critical match ip dscp af31 
class-map match-all video match ip dscp ef 

### The idea is each parameter is linked with its own parameters ###

I thought something like that "^interface"... "^class-map .. etc.

can you help me with that???...

  1. Try to post all possible keywords.
  2. On your second example you have a space after line-break. Is this a mistake or part of the configuration file?

Code:
head -2 input >>ouput
tail +3 input | { read prev
while read a
do
if [[ $prev = "!" ]]
then
        first=$a
else
        if [[ "$a" != "!" ]]
        then
                printf "%s %s\n" "$first" "$a"
        else
                if [[ $prev = $first ]]
                then
                        print "$first"
                fi
        fi
fi
prev=$a
done } >>ouput

euh ...
it wouldn't handle the case

Code:
!
class-map match-all critical
 match ip dscp af31 
class-map match-all video
 match ip dscp ef 
!

but only

Code:
!
class-map match-all critical
 match ip dscp af31 
!
class-map match-all video
 match ip dscp ef 
!

This is a near solution,,,,

Code:
awk '($1 != "!"){print $0}' router | awk 'END{print}/!/;{
if (/^class-map/ || /^policy-map/ || /^interface/ || /^router/ ||
/^route-map/ || /^ip classless/ || /^ip route/ || /^snmp/ ||
/^banner/ || /^line/ || /^end/){x=$0;next}else{print x,$0}}'

Its not perfet, but work.
