[Shell 1] nethogs

Displays processes sorted by network bandwidth usage in descending order. [Shell 1] shows the output of nethogs displaying network bandwidth usage per process. When PID is “?” and DEV interface is blank, it means packets are being processed by kernel threads that are unknown at the user level.

1.2. nethogs [Interface]

Displays only processes using [Interface].
