    Rocky Linux 9.4, bash
    This is useful for upgrading nodes (after upgrading the binaries) or changing certain options, such as --owner, etc (rpc, ports, logging level,…).

MAXPORT=33309

    echo ; echo "Replacing node with peer-id $i at port $iPORT..."
    iPID=$(lsof ~/.local/share/safe/node/$i/logs/safenode.log | grep "safenode " | grep -o "[0-9]*" | head -1)
    kill $iPID
    sleep 1
