From a discussion on Unix & Linux Stack Exchange:

lsof rocks my world! grep on IPv4 as well to find various IP based things

The lsof is a command you can ignore, but how about the rocks my world? What's the meaning of it?


1 Answer 1


Simple definition lookup (from Urban Dictionary):

rocks my world - When someone/something makes life so much better...

Indeed IPv4 addresses do (according to the abstract of a technical paper):

...we report on techniques and analyses that enable us to capture Internet-wide activity at individual IP address-level granularity by relying on server logs of a large commercial content delivery network (CDN) that serves close to 3 trillion HTTP requests on a daily basis. [emphasis added]

    I don't think IPv4 rocks anyone's world these days.
