UNU-SWAP(1)

💖 unu-swap — the manual page, bestie edition 💖

okay so this is unu-swap, and it lives in the User Commands section of the manual (section 1, iykyk). it's a lil baby subcommand situation and honestly? it's giving main character energy for a two-line job. let's go. 🦋

✨ NAME ✨

unu-swap — interchange ordering of two axes 💅

like... you have two axes. they're in an order. you want them in the other order. that's it. that's the whole vibe. 🔥

---

🌸 SYNOPSIS 🌸

unu swap -a,--axis <axisA axisB> [-i,--input <nin>] [-o,--output <nout>]

look at her. so simple. so clean. no cap. ✨

---

🎀 DESCRIPTION 🎀

Interchange ordering of two axes. it's literally a special case of unu-permute(1), which is the fancy general version — but if all you wanna do is flip two axes, why do extra work? this is the shortcut and she ate. 👑

• Uses nrrdAxesSwap (the actual machinery doing the heavy lifting, we're just the cute lil wrapper 🧚)

---

💅 OPTIONS 💅

• -a <axisA axisB>, --axis <axisA axisB> — the two axes to switch (0-based numbering) (2 unsigned ints). so like, 0 and 1, not 1 and 2 — we count from zero around here, periodt. 🔢
• -i <nin>, --input <nin> — input nrrd 📥 the file you're feeding in, bestie.
• -o <nout>, --output <nout> — output nrrd (string); default: "-" 📤 and ngl that default "-" means it goes to stdout, so you can pipe it straight into the next thing like the icon you are. 🌈

go read unu-permute(1) if you want the full menu of reordering options — she's the big sister. 🌟

fr fr bestie: axis numbering is 0-based. don't come at me with 1 and expect the first axis. not me making that mistake at 3am. 😭
