the command:
	route -n
should do the job. -n says's don't look up the DNS
names for addresses.

the default route will have a 'destination' of 0.0.0.0
and a 'genmask' of 0.0.0.0
In the example below, the gateway would be 192.168.86.254

] % route -n
] Kernel IP routing table
] Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
] 192.168.86.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0
] 127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
] 0.0.0.0         192.168.86.254  0.0.0.0         UG    0      0        0 eth0
