While I was composing the message, it looked like three lines; but I see
it is only two. The second line ends with 'done'.
More clearly:
if [ -f /var/lib/dhcp/dhclient.${1}.leases ]; then
grep 'option routers' /var/lib/dhcp/dhclient.${1}.leases | \
tail -n 1 | \
while read j1 j2 gateway; do
echo $gateway | sed 's/;//'
return 0
done
fi
