🌸 CASDOWNLOAD(1) — like, the whole vibe 🌸

okay bestie, sit down, hydrate, because we're doing casdownload(1) and honestly? it's giving "tiny command, huge list of flags." she downloads stuff from a CAS service and she does it beautifully. no cap. 💅

✨ NAME ✨

casdownload — literally just casdownload, she's not gonna over-explain herself, that's the name, periodt. 🫶

🦋 SYNOPSIS 🦋

casdownload

that's it. that's the whole synopsis. iconic minimalism. 🎀

💖 DESCRIPTION 💖

so basically she takes a digest (root, tree, action or file, pick your fighter) and drops it into a directory you tell her about. that's the whole plot. 🌈

heads up bestie: action digest download expects that the ActionCache is hosted on the same server as the CAS server. like, same server same server. don't come crying to me otherwise. 😭

and now the flags, in the exact order she gave them to us, no skips, no summary, we respect the list:

🍓 EXAMPLE USAGE 🍓

the way she showed us exactly how it's done, obsessed:

--destination-dir=/path/to/output --root-digest=deafbeef/123

and that's the whole page, bestie. go download your digests. you got this. iykyk. 💜🧚🌸
