Scan delle reti wifi presenti

iw wlan0 scan e un colpo di grep diocane:

Andiamo di awk

$1 == "BSS" {
    MAC = $2
    wifi[MAC]["enc"] = "Open"
}
$1 == "SSID:" {
    wifi[MAC]["SSID"] = $2
}
$1 == "freq:" {
    wifi[MAC]["freq"] = $NF
}
$1 == "signal:" {
    wifi[MAC]["sig"] = $2 " " $3
}
$1 == "WPA:" {
    wifi[MAC]["enc"] = "WPA"
}
$1 == "WEP:" {
    wifi[MAC]["enc"] = "WEP"
}
END {
    printf "%s, %s, %s, %s\n","SSID","Encryption","Signal","Frequency"

    for (w in wifi) {
        printf "%s, %s, %s, %s\n",wifi[w]["SSID"],wifi[w]["enc"],wifi[w]["sig"],wifi[w]["freq"]
    }
}

il risultato soddisfa:
