nbdkit-exitlast-filter(1)

💖 nbdkit-exitlast-filter — the manual page, bestie edition 💖

okay so this is nbdkit-exitlast-filter(1), from the NBDKIT manual section. it's a lil filter with main character energy and one job. let's get into it 🫶

---

✨ NAME ✨

nbdkit-exitlast-filter — exit on last client connection 💅

---

✨ SYNOPSIS ✨

nbdkit --filter=exitlast PLUGIN

---

✨ DESCRIPTION ✨

so "nbdkit-exitlast-filter" is an nbdkit filter that makes nbdkit exit when there are no more client connections. that's it. that's the whole vibe. 🦋

⚠️ but bestie, listen: it does not exit before the first client connection. like, it needs at least one client to come thru first before it starts counting down. no clients, no exit. periodt.

one use for this is pairing it with a superserver, so you save resources when nbdkit isn't in use (go look at nbdkit-service(1) for that). another use is making sure nbdkit exits after the client has finished — but lowkey, also check nbdkit-captive(1) for other ways to do the same thing 👀

and if you wanna exit when an event happens instead, run don't walk to nbdkit-exitwhen-filter(1) 🌈

---

✨ PARAMETERS ✨

there are no parameters specific to nbdkit-exitlast-filter. like, zero. none. 🙈

any parameters you do pass get passed through to and processed by the underlying plugin in the normal way. so they're not ignored, they're just not this filter's business 💁
