TCP/IP command. Add or remove entries in the routing tables maintained by routed. route accepts two commands: add, to add a route, and del, to delete a route. The two commands have the following syntax:
add [-net | -host] address [modifiers] del [-net | -host] address [modifiers]
address is treated as a plain route unless -net is specified or address is found in /etc/networks. -host can be used to specify that address is a plain route whether or not it is found in /etc/networks. Using route modifiers, you can specify the gateway through which to route packets headed for that address, its netmask, TCP mss, or the device with which to associate the route; you can also mask certain routes. Only a privileged user may modify the routing tables.
If no command is specified, route prints the routing tables.
Show numerical addresses; do not look up hostnames. (Useful if DNS is not functioning properly.)
Use netstat -r format to print routing table. Use twice to print extended information. Same as netstat -ree.
Print help message, then exit.
Specify an address family to use with an add or del command. family may be inet, inet6, ax25, netrom, ipx, ddp, or x25.
