The command "bmon -b" is used to launch the bmon interface in bandwidth mode.
Bmon is a command-line bandwidth monitor tool that displays real-time statistics about network bandwidth usage. It provides detailed information about data transfer rates, packet rates, and total network traffic for each network interface on your system.
By using the "-b" option, bmon enters bandwidth mode, which displays the bandwidth usage in a graphical format. This mode represents the data transfer rates using horizontal bars, where each bar's length corresponds to the amount of bandwidth utilized by that interface. The longer the bar, the higher the bandwidth usage.
Overall, "bmon -b" allows you to monitor and visualize the network bandwidth usage of your system in real-time.
