bash-4.4$ ozone sh key list -h
Usage: ozone sh key list [-hV] [-p=<prefix>] [-s=<startItem>] [[-l=<limit>] |
                         [-a]] <value>
list all keys in a given volume or bucket or snapshot
      <value>               URI of the volume or bucket.
                            Ozone URI could either be a full URI or short URI.
                            Full URI should start with o3://, in case of non-HA
                            clusters it should be followed by the host name and
                            optionally the port number. In case of HA clusters
                            the service id should be used. Service id provides a
                            logical name for multiple hosts and it is defined
                            in the property ozone.om.service.ids.
                            Example of a full URI with host name and port number
                            for a key:
                            o3://omhostname:9862/vol1/bucket1/key1
                            With a service id for a volume:
                            o3://omserviceid/vol1/
                            Short URI should start from the volume.
                            Example of a short URI for a bucket:
                            vol1/bucket1
                            Any unspecified information will be identified from
                            the config files.

  -a, --all                 List all results
  -a, --all                 List all results
  -h, --help                Show this help message and exit.
  -l, --length=<limit>      Maximum number of items to list
                              Default: 100
  -l, --length=<limit>      Maximum number of items to list
                              Default: 100
  -p, --prefix=<prefix>     Prefix to filter the items
  -s, --start=<startItem>   The item to start the listing from.
                            This will be excluded from the result.
  -V, --version             Print version information and exit.
