🌸 desync(1) — no literally bestie, this is the prune page 💅

Okay so real talk: the man page header says desync(1) (that's the family name, the whole desync squad 🫶), and this specific page is all about desync-prune. Yes, the pruning one. The "delete the stuff nobody's using" one. Buckle up 🎀

✨ NAME ✨

desync-prune — remove unreferenced chunks from a store 🧹💖

---

⭐ SYNOPSIS ⭐

desync prune <index> [<index>...] [flags]

---

🦋 DESCRIPTION 🦋

So here's the vibe: desync reads chunk IDs out of your index files, then deletes every chunk from a store that isn't referenced in any of the index files you handed it. That's it. That's the whole job. Iconic.

⚠️ Heads up bestie — this is a destructive operation. Like, chunks-gone-forever destructive. So by default you get a confirmation prompt before any chunks get yeeted, unless you pass --yes. (Use --yes responsibly, iykyk 🙈)

Also! You can pass - to read a single index from STDIN. Lowkey handy. 🌈

💅 OPTIONS 💅

• --ca-cert="" — trust authorities listed in this file instead of the OS trust store 🎀
• -r, --cache-repair[=true] — replace invalid chunks in the cache from source ✨
• --client-cert="" — path to the client certificate for TLS authentication 🔐
• --client-key="" — path to the client key for TLS authentication 🔑
• -n, --concurrency=10 — number of concurrent goroutines. Set it to -1 and let desync choose for you: the number of CPUs for chunking and hashing, adapting to each store up to 128 for transfers ⚡
• -e, --error-retry=3 — how many times to retry when a network error happens 😭
• -b, --error-retry-base-interval=500ms — the initial retry delay, which increases linearly with each subsequent attempt ⏳
• -h, --help[=false] — help for prune 🫶
• -s, --store="" — the store you wanna prune 🗂️
• -t, --trust-insecure[=false] — trust invalid certificates (yes, that's what it says 👀)
• -y, --yes[=false] — do NOT ask for confirmation before deleting chunks. main character energy, use with care 💀

👑 OPTIONS INHERITED FROM PARENT COMMANDS 👑

• --config="" — config file (default $HOME/.config/desync/config.json)
• --digest="sha512-256" — digest algorithm, either sha512-256 or sha256
• --verbose[=false] — verbose mode 🗣️

🔥 EXAMPLE 🔥

  desync prune -s /path/to/local --yes file.caibx
  desync prune -s /path/to/local current.caibx previous.caibx

First one: prune with zero questions asked (--yes, bold of you). Second one: prune using two index files at once so it keeps anything referenced by current.caibx or previous.caibx. Slay 🌸
