I need to know how to find the size of the kernel routing table.
I have knowledge that the routing table is stored in `/proc/net/route`.

I am presently using the command `wc` to count the number of characters in this routing file. But the problem is my routing table will contains thousands of entries and I need to be able to find the size of it very frequently.

Is the size of the routing file stored elsewhere?
How do I get to know the size of the file `/proc/net/route` efficiently?
