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.
