NVME-RPMB-READ-CO(1)

📦 version 3.2, in arch rolling

💅 NVME-RPMB-READ-CO(1) — like, the nvme manual page, bestie

okay so you found the man page for nvme-rpmb-read-counter in the NVMe Manual and honestly? it's a short one, so let's get into it 🎀

✨ NAME ✨

nvme-rpmb-read-counter — read the RPMB write counter. that's the whole vibe. it reads the counter. it's giving "one job, does it well" 💁‍♀️

🌸 SYNOPSIS 🌸

nvme [<global-options>] rpmb read-counter <device>
                        [--target=<target-id> | -t <target-id>]

lowkey a mouthful but we move 🫶

🦋 DESCRIPTION 🦋

okay so what this does: it reads the current write counter of the RPMB target you point it at. the counter value it reads gets printed straight to STDOUT, no cap, that's the output 💖

now the important bit — the <device> parameter is mandatory (not optional, not "eh maybe later", mandatory 😤) and you have to specify an NVMe character device, like literally /dev/nvme0. character device. not the block device. iykyk 💅

🎀 OPTIONS 🎀

  • -t <target>, --target=<target> — the RPMB target id, bestie. this should be one of the supported RPMB targets, the same ones that get reported by nvme rpmb info (go check that if you're unsure, it's right there). and if you don't give it anything at all? the default of 0 is used as the RPMB target. zero. default. iconic behavior honestly 🌈

👑 GLOBAL OPTIONS 👑

these ones live up at the top-level nvme command — they're defined there and they're available to this subcommand too. so yes you can use them here, they're not exclusive ✨

  • --dry-run — print the command that would be executed, but don't actually execute it. it's the "look but don't touch" of flags 🙈
  • --no-ioctl-probing — disable probing for 64-bit IOCTL support. that's it, that's the whole thing 🦋
  • --no-retries — disable retry logic on transient errors. one shot, no second chances 💀
  • -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, so don't get greedy 🍓
  • --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 to those versions 😭
  • --quiet — suppress informational messages. errors are still reported (they never get silenced, rude), and --quiet cancels any --verbose for the library log level. they cancel each other out, it's giving enemies to lovers 💜
  • --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. four keys, all listed, all slay 👑
  • --timeout=<ms> — set the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). so -1 is literally forever, choose wisely 🧚
  • -v, --verbose — increase the level of detail in the output. may be specified multiple times to further increase verbosity. stack it. go off. more -v more info 🔥
⭐ also bestie: these options can be set as machine-wide defaults in nvme-cli.conf(5). but a command-line flag always overrides the file. always. no exceptions. main character energy for the CLI flag 💅

💖 EXAMPLES 💖

  • read current write counter of RPMB target 0:
# nvme rpmb read-counter /dev/nvme0 --target=0

that's it. that's the example. and it ate 🍓
