CLI apps to check what's using your bandwidth

Just came across a number of very useful commands to figure out what slowing down your internet.
First is iftop which is similar to top, htop and iotop and breaks down all of the processes with internet connections.
Others are iptraf, netstat-p and nethogs.
Run them as sudo for more information. More details here.
For network devices other than the defauls eth0, run iftop and nethogs as

sudo iftop -i wlan0

sudo nethogs wlan0
