echo "Extracting hostnames to /etc/hosts.<room>"
declare -a rooms
devices=/etc/linuxmuster/sophomorix/default-school/devices.csv

## Step 1: Create /etc/hosts.$room by using the first entry in devices.csv (aka workstations)
rooms=( r219 r202 r302 rl r014 r015 r016 )
echo -n " - "
for room in "${rooms[@]}" ; do
    egrep -v -e"$EXCLUDE" $devices | grep "^$room;" | awk -F\; '{print $2}' > /etc/hosts.$room
    echo -n "$room, "
done
echo

## Step 2: Create more /etc/hosts.room manually:
echo "idle
chapman
booth
gilliam
jones
clay
" > /etc/hosts.vm
