How to remove all india IPs from a text file ?

[Deeresh]

Hi,

I have two files. The first one contains the list of all INDIA IPs (Subnets ) and the second one has list of IPs all countries.

I just want to remove all the INDIA IPs from the second file.

Please help me. Thanks in advance.

First sort them

Code: Select all

sort -u -t. -k1,1n -k2,2n -k3,3n -k4,4n <in.zone >in.zone.sorted
sort -u -t. -k1,1n -k2,2n -k3,3n -k4,4n <all.zone >all.zone.sorted

then filter out equal entries

Code: Select all

sdiff -ls in.zone.sorted all.zone.sorted

P.S. This actually works only for IPv4 addresses, but the concept is applicable to any IP type
