Hello Monks ..
I am a SysAd who has the task of consolidating a large file with IP Addresses... and what better than PERL for the same ..
I have been through the FAQs and got a few pointers with file operations, etc. What really kills me is the algorithm to do so as IP numbers have their own maths.
Well, here's hoping for enlightenment ..
Input File format : From address, To Address, Name
202.1.2.0,202.2.255.255,a
202.3.0.0,202.3.255.255,a
202.4.0.0,202.4.0.255,b

The above eg. shows that line 2 is the continuation of line one and as the name is the same, the o/p needs to be :

Output File format : From address, To Address, Name
202.1.2.0,202.3.255.255,a
202.4.0.0,202.4.0.255,b

I have tried using a lot of if's and ands, but I'm not able to pick 2 lines and check throughout the file. Thanks a lot.
