How to manage bitcoin-core by console in ubuntu 18.04

[yordanjr]

I have installed bitcoin-core by snap on Ubuntu 18.04, when running bitcoin-core through the interface it works perfectly, but I want to administer it by console, according to the documentation I should run "bitcoind -daemon", but when I do this I get the following message: "order not found. "

Note: bicoin core is installed in the path /home/username/snap/bitcoin-core/common/.bitcoin
