To check if l2geth is running correctly, open another command line window and run these commands:

/root/optimism/l2geth/build/bin/geth attach --datadir=/root/.local/share/optimism/l2geth/datadir

eth.blockNumber

Wait a few seconds and then look at the blocknumber again and exit:

eth.blockNumber

exit
