Couldn't find db or node.socket

HI - Trying to setup node for first time. Following this instructions
For below command, I can’t seem to find db or node.socket on my ubuntu file system.

cardano-node run
–topology path/to/mainnet-topology.json
–database-path path/to/db
–socket-path path/to/db/node.socket
–host-addr x.x.x.x
–port 3001
–config path/to/mainnet-config.json

can some one help?

I believe I got through above problem but now I am hitting another issue Network.Socket.bind: unsupported operation (Cannot assign requested address) - for main net

start the node with host-addr

worked. thx
