SNAP_NAME=$(curl -s https://ss.dymension.nodestake.org/ | egrep -o ">20.*\.tar.lz4" | tr -d ">")
curl -o - -L https://ss.dymension.nodestake.org/${SNAP_NAME}  | lz4 -c -d - | tar -x -C $HOME/.dymension

Start the service & check logs

sudo systemctl restart dymd && journalctl -u dymd -f -o cat | grep height
