I am working with a Dialog GUI.

./sdvpn.sh is the code for the GUI main menu, shown below.

./killvpn.sh is a script containing only one command, sudo pkill vpn

./region.sh is a Dialog menu allowing to specify the country you desire your VPN to connect to.

When I want to kill any active OpenVPN connections, I select option 2 on the menu below:

`#!/bin/bash



#Main Menu



HEIGHT=15

WIDTH=40

CHOICE_HEIGHT=4

BACKTITLE="VPN"

TITLE="Main Menu"

MENU="Choose an Option: "



OPTIONS=(1 "VPN Menu"

         2 "Kill Active VPN")



CHOICE=$(dialog --clear 

                --backtitle "$BACKTITLE" 

                --title "$TITLE" 

                --menu "$MENU" 

                $HEIGHT $WIDTH $CHOICE_HEIGHT 

                "${OPTIONS[@]}" 

                2>&1 >/dev/tty)



clear

case $CHOICE in

        1)

        cd ~/VPN/gui

        ./region.sh

        ;;

        2)

        cd ~/VPN/scripts

        ./killvpn.sh

        cd ~/VPN

        ./sdvpn.sh

        ;;



 esac`

This code for Option 2 is supposed to achieve the following:

• lead to my Scripts directory


• Exectute sudo pkill vpn
  


• Return to the main folder where my main menu.sh is kept


• Run the main menu, taking the process full circle.

The Problem

It will not return to the main menu, and I have no way to troubleshoot this. The same methodology worked perfectly when rolled out on Kali Linux 2018.2.

When I execute sudo pkill vpn or my killvpn.sh file, it simply kills the VPN connections as expected. However when running the same script from the Dialog GUI, I receive a message which says "Terminated."

I have tried rerouting the killvpn.sh to activate the Dialog GUI as part of its script, but the same problem occured.
I have then tried, with both sudo pkill vpn and killvpn.sh to include the sleep command, as I was simply returned to the terminal, and believed this was a process it could execute in order to continue running the code, but this failed too.

I am now unable to kill the VPN from my GUI, and I would like to know if there was a way I can either remove the "Terminated." message, or a way to accomplish my task. As a bonus ball, I would be grateful if someone could explain to me under what conditions will pkill vpn display this message, so I can avoid it in the future.

In this case, I found that using the command
sudo killall openvpn was both a more effective way of terminating OpenVPN Connections, and also avoided the dialog I got with sudo pkill vpn allowing me to return to the dialog menu without any issues.
