What is the primary function of the iwconfig command in Linux?

The primary function of the iwconfig command in Linux is to provide a command-line utility specifically designed for viewing and setting parameters related to wireless network interfaces. This utility focuses on configurations that affect wireless operations, such as SSID (the network's name), frequency, mode, and other network-specific settings necessary for wireless connectivity.

By using iwconfig, users can make adjustments to their wireless interfaces to optimize performance, troubleshoot connectivity issues, and configure necessary parameters for successful wireless communication. This makes iwconfig an essential tool for users working with wireless networks in Linux environments. The other options relate to different functionalities within the Linux system, such as firewall management, system performance monitoring, and disk partitioning, but do not pertain to wireless configuration tasks.
