To create an sequential znode using the Zookeeper Java Shell, we have to specify the - flag in the createcommand.

To create a sequential znode using the ZooKeeper Java Shell, we have to specify the `-s` flag in the `create` command.

For example, the following command creates a sequential znode named "myznode" in the root directory "/":

create -s /myznode "data"

The `-s` flag tells ZooKeeper to append a monotonically increasing sequence number to the end of the znode name. The resulting znode name will be something like "/myznode000000001" or "/myznode000000002", depending on the order in which the znodes are created.
