ProcessRunner.GetProcessOutputAsync is not working

[edmundormz]

This is the code being used (From RaspberryIO Playground):

` public bool SetupWirelessNetwork(string adapterName, string networkSsid, string password = null)
{
var payload = "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev\nupdate_config=1\n";

        payload += string.IsNullOrEmpty(password) ?
            $"network={{\n\tssid=\"{networkSsid}\"\n\t}}\n" :
            $"network={{\n\tssid=\"{networkSsid}\"\n\tpsk=\"{password}\"\n\t}}\n";

        try
        {
            File.WriteAllText("/etc/wpa_supplicant/wpa_supplicant.conf", payload);
            ProcessRunner.GetProcessOutputAsync("ifconfig >> /home/pi/ifconfig.txt");
            //ProcessRunner.GetProcessOutputAsync("sudo pkill -f wpa_supplicant >> /home/pi/Documents/kill_wpa.txt");
            //ProcessRunner.GetProcessOutputAsync("sudo wpa_supplicant", $"-B -D wext -i {adapterName} -c /etc/wpa_supplicant/wpa_supplicant.conf >> /home/pi/Documents/run_wpa.txt");
        }
        catch
        {
            return false;
        }

        return true;
    }`

After a while testing on raspberry, realized the "ProcessRunner.GetProcessOutputAsync" does nothing at all. Used the line "ProcessRunner.GetProcessOutputAsync("ifconfig >> /home/pi/ifconfig.txt");" to be sure and it did not created any file, but command worked on command line.

Am I using this the wrong way?

for starters, an async operation has to be awaited or it's result retrieved in order for it to do anything at all... NOOBZ

You´re ritght
My mistake
Fixed like this:
ProcessRunner.GetProcessOutputAsync("pkill", "-f wpa_supplicant").Wait();
