Re: What is wrong with my `nmcli device status`?

[ToddAndMargo via users <users@xxxxxxxxxxxxxxxxxxxxxxx>]

Followup: I create a number of bash functions to
handle the task(s).   Thank you all for the help!


function GetIP () {
    echo "$(ip -f inet route | grep -i $InetDev | grep -i src | awk 
'{print $9}')"
}


function CheckInternetStatus () {
    local GoogleDNS="8.8.8.8";
    local RtnStr="$( ping -W .1 -c 1 $GoogleDNS | grep loss );"
    # echo "RtnStatus = <$?>   RtnStr = <$RtnStr>"  > "/dev/tty"
    if  [[ "$RtnStr" == *", 0% packet loss"* ]]; then
       echo "UP"
    else
       echo "DOWN"
    fi
}


function GetPublicIP () {
    local WIP=$(dig +short myip.opendns.com @resolver1.opendns.com)
    # echo "WIP = <$WIP>" > "/dev/tty"
    if [[ "$WIP" == *"not found"* || "$WIP" == *"no servers could be 
reached"* ]]; then
       WIP="Not Found"
    fi

    echo $WIP
}


function GetGW () {
    echo "$(route -n | grep eno2 | grep UG | sed -n 1,1p | awk '{print 
$2}')"
}


function UpDownedEthernetDevices () {
   local State=""
   local LinkState=""

   for Line in $(nmcli device | grep ethernet | awk '{print $1}'); do
       State="$(nmcli device | grep $Line | awk '{print $3}')"
       LinkState="$(ip address | grep eno2 | awk -F "," '{print $3}')"
       # echo "Line = <$Line>   State = <$State>   LinkState = 
<$LinkState>')" > "/dev/tty"

       if [ "$State" == "disconnected" ]; then
          echo "Reconnecting $Line" > "/dev/tty"
          /usr/bin/nmcli device     disconnect $Line
          /usr/bin/nmcli device        connect $Line
          /usr/bin/nmcli connection down $Line
          /usr/bin/nmcli connection up   $Line

       elif  [[ $LinkState == "DOWN" ]]; then

          beesu "ip link set $Line down; ip link set $Line up;"

          /usr/bin/nmcli connection down $Line
          /usr/bin/nmcli connection up   $Line
       fi
   done

   NotifySound
