Hi there.
I have a similar requirement to extract a specific piece information from
the output of a Linux command. I'm running a iwlist to get all BSSID names
(ESSID field). Here's the code followed by the output:
iwlistCmd := exec.Command("iwlist", iface, "scan")
iwlistCmdOut, err := iwlistCmd.Output()
if err != nil {
fmt.Println(err, "Error when getting the interface information.")
} else {
fmt.Println(string(iwlistCmdOut))
}
Output sample:
wlan0 Scan completed :
