NVME-PRIMARY-CTRL-CAPS(1)

🌸 NVME-PRIMARY-CTRL-CAPS 🌸

okay bestie, so this page is nvme-primary-ctrl-caps — that's the manual name, and it lives in the NVME-PRIMARY-CTRL family 💅. Yes it's a long one, no we're not scared of it.

💖 NAME 💖

nvme-primary-ctrl-caps — Send identify Primary Controller Caps, return result and structure (deprecated) 🫶

✨ SYNOPSIS ✨

nvme [<global-options>] primary-ctrl-caps <device>

🦋 DESCRIPTION 🦋

So here's the tea: this is a deprecated alias for nvme-id-primary-ctrl-caps(1), and it's still hanging around for scripts written against nvme-cli versions older than 3.0. The options and behavior are literally identical — the only thing being kept is the top-level command name. Same energy, different name 😌

New scripts should use nvme id primary-ctrl-caps instead, fr fr. This alias prints a deprecation warning on stderr and may be removed in a future release — so like, don't get attached 💀

See nvme-id-primary-ctrl-caps(1) for the full option reference. That's the main character now 👑

🌈 GLOBAL OPTIONS 🌈

These options are defined at the top-level nvme command and are available to this subcommand — so they show up to the group chat even though they're technically not this subcommand's friends:

• --dry-run — print the command that would be executed, but don't actually execute it. It's giving window shopping 🛍️
• --no-ioctl-probing — disable probing for 64-bit IOCTL support.
• --no-retries — disable retry logic on transient errors. One shot, no takebacks 🙈
• -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 — pick one, bestie, you can't have all four 🎀
• --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 — sorry, not on the list 💅
• --quiet — suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level. It's the "muted but still watching" setting 🤫
• --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). No clock, no stress 💀
• -v, --verbose — increase the level of detail in the output. May be specified multiple times to further increase verbosity. Spam that flag, it's iconic ✨

These options can also be set as machine-wide defaults in nvme-cli.conf(5). A command-line flag always overrides the file — CLI is the main character here, periodt 👑
