💖 bup-demux(1) — like, the girlies' guide to demultiplexing ✨

🌸 NAME 🌸

bup-demux — demultiplexes data and error streams from standard input. that's it, that's the whole vibe 🎀

---

⭐ SYNOPSIS ⭐

bup demux

---

🦋 DESCRIPTION 🦋

⚠️ bestie, listen — this is an internal command, and it may be removed or changed at any time. not "eventually", not "after a deprecation cycle", like… any time. do not build your whole personality around her, okay? 😭

so check it: bup demux reads standard input as a bup "multiplexed" stream — that's data from standard output and standard error jammed together into one glorious combo platter — and then it reproduces that output on its own standard output and standard error. she splits the streams back apart. she's literally doing the un-mixing. icon behavior 👑

her primary purpose is to support bup-on(1). that's who she shows up for. bup-on(1) girlies, this one's for you 🫶
