Thanks to everyone for the quick responses. However, I made a crucial mistake when I showed what it needs to become. What I actually need to change it to needs to be `ip vrf forwarding ABC:Defgh ip address 1.1.1.1 255.255.255.252 ip address 1.1.1.1 255.255.255.100 ip vrf forwarding ABD: Efghi ip address 2.2.2.2 255.255.255.252 ip address 2.2.2.2 255.255.255.100` [download] The last part of the duplicated line needs to change as it is being copied. Is there any way of doing this?	[reply] [d/l]

Change the code given above to: `perl -pe'$_ .= $_, s/252$/100/ if /^ip address/'`	[reply] [d/l]
