Which command will show the configuration details of a wireless connection in Linux?

The command that shows the configuration details of a wireless connection in Linux is "iwconfig." This utility is specifically designed to display wireless network interfaces and their associated parameters. When executed, it provides information such as the SSID (network name), signal strength, bit rate, frequency, and the encryption method used for the wireless connection.

In contrast, "ifconfig" is an older command that is used to configure and display network interfaces on Unix-like operating systems, including both wired and wireless connections. However, it does not provide specialized details for wireless connections that are specific to the nuances of wireless networking.

"ipconfig" is primarily a Windows command that displays the configuration of network interfaces, including their IP addresses, subnet masks, and default gateways, but it does not apply to Linux systems.

"grep" is a command-line utility used for searching plain-text data for lines that match a regular expression. While it can be used in conjunction with other commands to filter their output, it does not directly provide configuration details for wireless connections.

Therefore, utilizing "iwconfig" is the most appropriate method for obtaining comprehensive details about wireless network settings on a Linux system.
