Shell script detect APs and Mac Address

My goal is to develop a script in a Linux (Kali Linux) environment that automates certain tasks such as running, detect Access Points showing me the signal strength and Mac Address as well as the clients that are connected.

I do not care what kind of encryption the goal is not invasion but anti-invasion. Once I get this information, I can decide on which APs and clients should direct the deactivating action.

If there is any script like this and you can leave a link or copy of the code. I am very grateful. If colleagues do not know, I also accept the help of someone who is knowledgeable.

It's not college work or even for professional purposes. For exclusive use only.

Note: I already have a code snippet that detects my Mac address to make a comparison later and prevent myself from being debugged from AP .

You can use the iwlist utility with the argument scan to list all APs within the reach:

$ sudo iwlist wlan0 scan

Output:

And you can filter only the ESSID , MAC Address and signal information ( Quality , Signal level and Noise level ) through the grep utility:

$ sudo iwlist wlan0 scan | grep "Address\|ESSID\|Quality"

Output:

  Cell 01 - Address: 00:1F:F3:02:04:81
            ESSID:"Apple Network"
            Quality=42/100  Signal level:-84 dBm  Noise level=-127 dBm
  Cell 02 - Address: 00:1D:7E:F8:15:F8
            ESSID:"42"
            Quality=58/100  Signal level:-73 dBm  Noise level=-127 dBm
  Cell 03 - Address: 00:1E:E5:65:C4:89
            ESSID:"Adkins"
            Quality=84/100  Signal level:-49 dBm  Noise level=-127 dBm
