Found a cool way to do a script (by Sparhawk in StackExchange) so that if you use sudo more than once or if a command requires you to enter your password, you should only have to enter it once.

I've used it already in my TCServer_restart.sh script and it works great!

sudo_done="/tmp/sudo.finished"
sudo_me() {
 while [ ! -f $sudo_done ]; do
  sudo -v
  sleep 5
 done &
}

stop_sudoing() {
  touch $sudo_done
  sleep 7
  rm $sudo_done
}

sudo_me &
#### Your script here.
stop_sudoing &

Just replace/add your stuff at the "# Your script here." and away you go!

There might be a way to have this in a separate bash script and then just include it into your script. It seems that the sudo_me & and the stop_sudoing & are what you would need to have explicitly in your script (after including the other, obviously).

If I use this more, I'll probably do something like that.
