The command "iw dev ${wlp} scan" is used to scan for available wireless networks using the "iw" command-line utility. Here is a breakdown of the command:

• "iw": This is the command-line utility to configure and view wireless network interfaces on Linux.
• "dev": This parameter is used to specify that we want to perform operations on a specific wireless device.
• "${wlp}": This is a placeholder that represents the name of the wireless network interface device. It could be something like "wlan0" or "wlp3s0". The actual name may vary based on the system configuration.
• "scan": This is the operation we want to perform, which is scanning for available wireless networks.

By running this command, the system will initiate a wireless network scan on the specified network interface, and it will display information about the available networks, including their respective SSIDs (network names), signal strengths, frequencies, and security protocols.
