NVME-ID-UUID(1)

💅 NAME 💅

okay so hi bestie 💖 welcome to the NVME-ID-UUID(1) page from the NVMe Manual — this one is all about nvme-id-uuid, which sends an Identify UUID List command to the device you specify. slay.

---

✨ SYNOPSIS ✨

nvme [<global-options>] id uuid <device> [--raw-binary | -b]

🦋 DESCRIPTION 🦋

This sends an Identify UUID List command to the specified device and returns the results, no cap. 🫶

The <device> parameter is mandatory, and it may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1). pick your fave 💅

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

⚠️ deprecated-alias tea: the bare nvme id-uuid form (without a space) still works as a deprecated alias and will be removed in a future major version. New scripts should use nvme id uuid instead. 💀✨

🎀 OPTIONS 🎀

• -b, --raw-binary — Print the raw buffer to stdout. Structure is not parsed by program. This overrides the vendor specific and human readable options. it's giving "just gimme the bytes" 🔥

🌈 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. fake it till you make it, but safely 🧚
• --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. Other versions are rejected.
• --quiet — Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.
• --set-options=<key=value>[,<key=value>...] — Set libnvme library options for this invocation. Supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — Set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). the way that timeout can just vibe forever 😭
• -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 🍓

• Have the program issue an id-uuid to display the structure.

# nvme id uuid /dev/nvme0

Part of the nvme-user suite. iconic, honestly 🌟
