Re: Matching a cisco interface config

Try

#! perl -slw
use strict;

$/ = "!\n"; ## set the delimiter

while( <DATA> ) {
    print "'$_'";
}

__DATA__
interface GigabitEthernet6/10
 description TRUNK-KBV-SW001
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,30,31,45,156-158
 switchport mode trunk
 switchport nonegotiate
!
interface GigabitEthernet6/11
 description Offices
 switchport access vlan 31
 spanning-tree portfast

This solution works, but in practice it would require some prepping of the config file, since I failed to mention it doesn't contain just the interfaces but a lot of other config settings as well. (As most Cisco configs do) I'll see how the regex approach below works in practice on a really big collection of configs and if I get into trouble with performance then this is probably the way to go.

Something like this? `#! perl -slw use strict; $/ = "!\n"; while( <DATA> ) { next unless m[^interface]; print "'$_'"; } __DATA__ interface GigabitEthernet6/10 description TRUNK-KBV-SW001 switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,30,31,45,156-158 switchport mode trunk switchport nonegotiate ! stuff with more stuff ! interface GigabitEthernet6/11 description Offices switchport access vlan 31 spanning-tree portfast ! thing with other things ! interface GigabitEthernet6/12 !` [download] Outputs: `C:\test>junk 'interface GigabitEthernet6/10 description TRUNK-KBV-SW001 switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,30,31,45,156-158 switchport mode trunk switchport nonegotiate !
