iftop: Show the bandwidth usage of a given interface.
$ sudo iftop -i ${interface}
try on your machine
The command "sudo iftop -i ${interface}" is used to launch the iftop tool with superuser privileges (via sudo) to monitor network traffic on a specific network interface.
Here's a breakdown of the command:
- "sudo": It is a command that allows a user to run programs with the security privileges of another user, typically the superuser (root).
- "iftop": It is a tool used to display an interactive display of network traffic on a given network interface.
- "-i ${interface}": This is an argument passed to the iftop command that specifies the network interface to monitor. The ${interface} is a placeholder that should be replaced with the actual name of the network interface you want to monitor (e.g., eth0, wlan0, etc.).
In summary, this command with proper replacement of ${interface} will run the iftop tool with root privileges, providing an interactive view of network traffic on the specified network interface.
