difference between netstat and ss in linux?

Question

In linux, netstat command tells us information of active sockets in system.

I understand that netstat uses /proc/net/tcp to acquire the system

Answer 1

I've made a comparison table (in Google Docs) (light HTML link) for converting between netstat and ss arguments. It's too big to include and update it here.

The short version of difference between short arguments is:

Arguments that require attention: r N i g M W T v C F c A U 2 f

Arguments that are safe to leave as is: h V l a n Z s p e o 4 6 x t u S w
