in reply to How to duplicate lines

Something like this?
#!/usr/bin/perl use strict; while (my $line = <DATA>) { print $line; if ( $line =~ /\sip address/ ) { $line =~ s/(\d+.\d+.\d+.)252/${1}100/; print $line; } } __DATA__ ip vrf forwarding ABC:Defgh ip address 1.1.1.1 255.255.255.252 ip vrf forwarding ABD: Efghi ip address 2.2.2.2 255.255.255.252

[Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
[Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
[Corion]: Cosmic37: Basically, you read one file into a hash, keyed by your key, and then match the lines from the second file to that hash
[Cosmic37]: note that the two files only have datetimes which may match whereas other data per line is different format in file1 and file2 - is that really intersection?
[jedikaiti]: Hi Monks
[Corion]: Cosmic37: Well, if you want to use only parts of a line for the key, see split or whatever other mechanism to extract the key from the line
[Corion]: Hi jedikaiti!
[Cosmic37]: is there a webpage for full CB for this chat rather than side panel chat?
[Cosmic37]: thank you for advice
[Cosmic37]: peach greets jedi
