Is there a way to access information available in

ip route show

command via some special file (or other method), the same way that output of

route -n

can be read from /proc/net/route? I know that I can just parse the output, but I am looking for something in more machine-readable format.

strace shows ip route show creating a NETLINK_ROUTE socket to get that: http://man7.org/linux/man-pages/man7/netlink.7.html

What specific information are you trying to get?

This is the perfect thing to use either cut, awk to pull the specific fields you want out of it.

Example:

ip route show |  awk '{print $1 " " $9 }' 

Returns network subnet and source IP.

Same information is on "/proc/net/route". You could check that file, instead of capture standar output information from "netstat -n" command.
