How to get the IPV4 address for an interface from /proc
Clash Royale CLAN TAG#URR8PPP
Is there a clean, simple way to get an IP address for a network interface from /proc, similar to the way I can get the MAC address for a network interface?
Ideally I would just type cat /proc/<foo>/interface_name and get the IPv4 address.
I'd rather not run anything other than cat.
linux ip proc

Under the /proc directory, you can also find the IPv4 addresses in the Forwarding Information Base table, at /proc/net/fib_trie
The table is pretty intelligible doing a mere cat, first comes the Main: and then Local:
cat /proc/net/fib_trie
or to see your network, IP addresses and netmask:
cat /proc/net/fib_trie | grep "|--" | egrep -v "0.0.0.0| 127."
|-- 193.136.1.0
|-- 193.136.1.2
|-- 193.136.1.255
|-- 193.136.1.0

They appear in a pre-determined order; probably priority, but that can be changed; other than that, no.

There's no way to associate ip addresses with interface in fib_trie.
