UNYAFFS(1)

✨ UNYAFFS ✨

okay bestie, so this is unyaffs — a lil command-line baddie from the General Commands Manual section (section 1, for the girlies who track these things 💅). she opens up YAFFS2 file system images and pulls the files right out of them. no cap.

🎀 SYNOPSIS 🎀

unyaffs [options]<image_file_name>[<extract_directory>]

like… yes, the spacing is literally that. it's giving "no spaces between things" energy. we move. 🫶

🌸 DESCRIPTION 🌸

so here's the tea, bestie: unyaffs extracts files from a YAFFS2 file system image. that image was made with mkyaffs2image — that's the tool that put the files in, and unyaffs is the girl who gets them back out. it's a whole cycle. iconic. ✨

you hand her the image file, and optionally a directory to dump everything into, and she does her thing. main character energy fr fr. 👑

💖 OPTIONS 💖

• -d — detect the flash layout. that's it. she'll look, she'll figure out the vibe, but she will not extract anything. all snooping, zero commitment. 🙈
• -b — the spare area contains bad block information. telling her this is lowkey important if your image is built that way.
• -c <chunk size> — set the chunk size in KByte. default is autodetect, and the max is 16. don't try to go bigger, she will simply not.
• -s <spare size> — set the spare size in Byte. default is autodetect, and the max is 512. same rules, bestie.
• -t — list the image contents. just the names, just the tour, no unpacking. like scrolling someone's camera roll instead of actually downloading it. 📸
• -v — verbose output. she will tell you everything she's doing. some might say too much. we say she's communicating. 💀
• -V — print version information. the classic "who are you and when were you born" check. 🎀

ok real talk for a sec: <chunk size> goes in KByte and caps at 16, <spare size> goes in Byte and caps at 512. those are the ceilings, so don't be out here trying to pass a bigger number and expecting a miracle. ⭐

🦋 SEE ALSO... jk there isn't one 🦋

ngl there's no SEE ALSO section in this page, so… nothing to link. we're self-sufficient. independent. thriving. 💜

and that's the whole page, bestie!! this one's from the General Commands Manual, dated March 23, 2013 — so she's been serving since 2013 and still ate. periodt. 🌈👑💅
