The command sudo iftop -b is used to run the network bandwidth monitoring tool called iftop with administrative privileges.

Here's a breakdown of the command:

• sudo is a command used in Unix-like operating systems to run a command with root privileges, allowing administrative access.
• iftop is a command-line tool that provides real-time monitoring of network traffic. It displays a continuously updated list of network connections, their source and destination IP addresses, and the data transfer rates in terms of bandwidth.
• -b is an option or flag specific to the iftop command. In this case, it stands for "bytes mode" and instructs iftop to display the bandwidth information in bytes per second instead of the default bits per second.

By running this command with administrative privileges, you can monitor network traffic and bandwidth usage in real-time using iftop.
