insmod regexp

for device in (*); do
  if probe --set=label --label "$device"; then
    menuentry "Boot from label $label" "$device" "$label" {
      root="$2"
      # $2 in this context is the second argument we passed to the
menuentry function.
      label="$3"

      linux /path/to/vmlinuz kernel arguments here root=LABEL="$label"
      initrd /path/to/initrd
    }
  fi
done
