What is the purpose of the 'iwconfig' command in Linux?

To view the status of wireless network interfaces
To configure wireless networks
To display all wireless connections
To disable wireless interfaces

The correct answer is: To view the status of wireless network interfaces

The 'iwconfig' command is used specifically to view the status of wireless network interfaces in Linux. This means that it shows information such as the connection strength, bit rate, and signal quality of wireless networks that are currently in use. It also displays the configurations of the interfaces, such as the SSID and security settings. Option B is incorrect because it is the 'ifconfig' command that is used for configuring wireless networks. Option C is incorrect because 'iwconfig' only shows the status of currently connected networks, not all wireless connections available. Option D is incorrect because disabling wireless interfaces is done through a different command, 'rfkill'.
