NVME-WDC-CAPABILIT(1)

💖 NAME 💖

Okay bestie, welcome to NVME-WDC-CAPABILIT(1) — aka the nvme-wdc-capabilities page from the NVMe Manual — and it is literally here to display WDC plugin command capabilities. Slay. ✨

🦋 SYNOPSIS 🦋

nvme [<global-options>] wdc capabilities <device>

🌸 DESCRIPTION 🌸

For the NVMe device you give it, this displays a list of commands and their support status. Iconic behavior, no cap. 💅

The <device> parameter is mandatory and has to be an NVMe character device (ex: /dev/nvme0). Not optional, bestie.

On success it returns 0, error code otherwise. Periodt.

🎀 OPTIONS 🎀

🌈 GLOBAL OPTIONS 🌈

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

• --dry-run — prints the command that would be executed, but does not actually execute it. It’s giving preview mode. 🙈
• --no-ioctl-probing — disables probing for 64-bit IOCTL support.
• --no-retries — disables retry logic on transient errors.
• -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time. Pick one, okay? 🎯
• --output-format-version=<version> — selects the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names. Other versions are rejected. No exceptions. 💀
• --quiet — suppresses informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff).
• -v, --verbose — increases the level of detail in the output. May be specified multiple times to further increase verbosity. Loud and proud. 🔥

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

👑 EXAMPLES 👑
