@IRJ said in List Comparison Tool:
I have two very large lists of IPs and I would like to compare the differences between the list. I usually use Notepad ++ Compare for this type of thing, but I believe it only compares line to line.
I also tried using conditional format in excel, but I am not sure if the results are accurate.
Just one command:
diff <(sort list1 | uniq) <(sort list2 | uniq).
For 95% of tasks involving text manipulation (from the easiest like this to mid-complexity), the standard unix tools can do everything in a very quick and concise way.
The other 4.95% (very complex, special stuff) can be handled by Python (but also ruby or perl).
The last 0,05% is HPC/realtime/weird (C, Ada, erlang?).
But please, don't use a giant piece of bloatware just to compare strings ðŸ˜.
