✨ NAME ✨

lblk-write-dir — writes directive specific data and optionally metadata 💅

🦋 SYNOPSIS 🦋

lblk write-dir <uri> [<args>]

💜 DESCRIPTION 💜

Writes directive specific data and optionally metadata. That's the whole vibe, no cap. You point it at a device, you tell it where to write, you hand it the goods. Simple. Iconic. 🎀

These ones are non-negotiable, bestie. No skipping.

  • <uri> — the Device URI, like '/dev/nvme0n1', '0000:01:00.1', '10.9.8.1.8888', or '\.PhysicalDrive1' 🙈
  • --slba 0xNUM — Start Logical Block Address. Where the party begins. 📍
  • --nlb NUM — Number of LBAs. ⚠️ NOTE: this is a zero-based value, so heads up, the math is mathing differently than you might expect.
