PS:

Theory often vs praxis, an not audio related example:

$ grep pppoe_off\( -A4 /usr/local/sbin/alice
pppoe_off() {
  echo; poff -a; ip link set enp3s0 down; printf "Progress: "
  while pidof pppd > /dev/null; do printf "."; sleep 3; done;
  echo; modprobe -vr pppoe; echo
}

There might be smarter ways to handle it in praxis (I'm not using this
script anymore), but actually not everything that should work by
theory, does the job in real life.
