What is the purpose of the echo command in the provided network scanning script?

The purpose of the echo command in a network scanning script is to display information to the user, often providing feedback on the current status or results of the scanning process. This can help users understand what the script is doing at any given time, such as indicating the progress of scanning IP addresses, showing errors, or confirming the completion of certain tasks. The echo command is essential for improving user experience by providing visibility into the script's operations, making it easier to track what is happening without needing to delve into the code itself.

In contrast, initiating a firewall is not related to the echo command, as it involves managing network security settings rather than providing output. Similarly, terminating the script would involve a different command or function, and importing libraries pertains to including external functions or capabilities within the script, which is unrelated to the echo command as well. The echo command primarily focuses on displaying text output and enhancing user interaction with the script.
