For more details, see The Future of Bandwhich #275 . How does it work? bandwhich sniffs a given network interface and records IP packet size, cross referencing it with the /proc filesystem on linux, lsof on macOS, or using WinApi on windows. It is responsive to the terminal window size, displaying less info if there is no room for it.
