What does the iwlist command accomplish?

The iwlist command is specifically designed to provide detailed information about wireless networks. One of its primary functions is to scan for and identify nearby Wi-Fi networks, displaying relevant information such as the network name (SSID), signal strength, and encryption type. This capability is particularly useful for users who want to troubleshoot or select a Wi-Fi network to connect to, as it provides a straightforward overview of available wireless access points in the vicinity.

In contrast, the other choices describe functionalities related to different command categories. For example, commands that list all network routes focus on routing information, while those that display file permissions are concerned with managing file access control. Additionally, commands that show currently running processes pertain to monitoring and managing system operations. Thus, the proper function of the iwlist command distinctly aligns with identifying and listing nearby Wi-Fi networks, making it the correct answer.
