The command "vnstati --hours --iface ${network_interface} --output ${path-to-output-png}" is used to generate an hourly network traffic report using the package called "vnstati" in Linux.

Here is what each part of the command means:

• "vnstati" is the name of the package or program that is being executed.
• "--hours" specifies that the generated report should be in hourly intervals, showing the network traffic for each hour.
• "--iface ${network_interface}" specifies the network interface for which the traffic report is generated. The ${network_interface} is a placeholder for the actual network interface (e.g., eth0 or wlan0).
• "--output ${path-to-output-png}" specifies the path and filename for the generated PNG image that will contain the network traffic report. The ${path-to-output-png} is a placeholder for the actual path and filename.

In summary, when you execute this command with the appropriate network interface and output file path, the "vnstati" program will generate a PNG image file that displays the network traffic on the specified network interface, with data organized in hourly intervals.
