I'm trying to get the details of the WiFi network that I've connected to. I have already tried iwlist wlan0 scan which give the details of the connected network as well as all the available networks too. And it also take nearly 5 seconds to get the data in the terminal. I also tried iw dev wlan0 link which gives the exact details that I required but it lacks to provide the signal quality (in percentage). So is there any command which would give the details of the wifi network like Essid Name, Address, Signal Quality, Signal Strength(RSSI).

Commands I've tried:

sudo iwlist wlan0 scan, the output is

          wlan0     Scan completed :

Another Command is sudo iw dev wlan0 link,

the output is **

You can try nmcli d wifi which does not require sudo privilege. This gives some of the information you want, and lists all networks, but the connected one has an asterisk so you can use grep to get only the headers and the line you want like so:

$ nmcli d wifi | grep ^\*
*  SSID                    MODE   CHAN  RATE       SIGNAL  BARS  SECURITY         
*  SKY5952D                Infra  11    54 Mbit/s  73      ▂▄▆_  WPA2
