Which short command to only output the IPv4 routing table? $ netstat -nr is great for outputting the Mac OS X IP routing tables.

However its output is long as it contains both IPv4 and IP6 routing tables.

Sometimes I wish to output only the IPv4 routing table. I wish to use short terminal command to only see the IPv4 routing table.

My best result is $ netstat -nr | sed -e '1,3d;/Internet6:/,$d;/^$/d' 

Can this command be shortened?
$ netstat -nr -f inet
