NAME
       nvme-registry-retrieve - Read an attribute from a controller's registry
       entry

SYNOPSIS
       nvme [<global-options>] registry retrieve <device>
                               --attr=<ATTR> | -a <ATTR>

DESCRIPTION
       Read a single attribute from the ownership registry entry for an
       NVMe-oF controller. The registry is stored under /run/nvme/registry/ as
       one directory per live controller, with one plain-text file per
       attribute (e.g. /run/nvme/registry/nvme3/owner).

       The <device> is the NVMe controller name (e.g. nvme3), given as a
       positional argument; the /dev/ prefix is optional.

OPTIONS
       -a <ATTR>, --attr=<ATTR>
           Attribute name to retrieve (e.g. owner, note). Required.

GLOBAL OPTIONS
       The following options are defined at the top-level nvme command and are
       available to this subcommand:

       --dry-run
           Print the command that would be executed, but do not actually
           execute it.

       --no-ioctl-probing
           Disable probing for 64-bit IOCTL support.

       --no-retries
           Disable retry logic on transient errors.

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, tabular, 'json, or binary. Only
           one output format may be used at a time.

       --output-format-version=<version>
           Select the output format version. Version 1 uses the original field
           naming, while version 2 (default) provides more consistent and
           script-friendly field names.

       --timeout=<ms>
           Set the timeout for the command in milliseconds.

       -v, --verbose
           Increase the level of detail in the output. May be specified
           multiple times to further increase verbosity.

       These options can also be set as machine-wide defaults in
       nvme-cli.conf(5). A command-line flag always overrides the file.

EXAMPLES
       o   Retrieve the owner of nvme3:

               # nvme registry retrieve nvme3 --attr owner
               stas
