DUMP.SSDFS(8)

📦 version 4.68, in nixos 26.05, nixpkgs unstable

💅 DUMP.SSDFS(8) — like, the dump.ssdfs page, bestie

okay so this is the man page for dump.ssdfs, section 8 of the manual (system administration commands, very official), and it's literally the tool that lets you peek inside an SSDFS file system and see what's actually going on in there. no cap. 🔍✨

🌸 NAME 🌸

dump.ssdfs — dump volume of SSDFS file system

🦋 SYNOPSIS 🦋

dump.ssdfs [options] device

that's it. options first, device last, main character energy the whole way through. 💅

🎀 DESCRIPTION 🎀

so dump.ssdfs dumps segments' content of an SSDFS file system from a given device or image file. like, it goes in and pulls out the actual bytes. 🫶

this utility allows inspection of SSDFS file system structures and can extract raw data or parse specific components like headers, logs, bitmaps, and mapping tables. it's giving forensic detective but make it cute. 🔥

✨ OPTIONS ✨

  • -d, --debug — Show debug output. all the messy little details, for when you need to actually understand what's happening. 💀
  • -g, --granularity — Show key volume's details (default operation). this is the vibe check mode — if you don't pick anything, you get this one. 👑
  • -h, --help — Display help message and exit. the classic "help me help you" flag. 🙈
  • -o, --output-folder _folder_ — Define output folder for dumped files. bc dumping everything into your cwd is lowkey chaos. 🍓
  • -p, --peb _id=value,peb_count=value,size=value,..._ — Show PEB dump. Full syntax includes: id=value,peb_count=value,size=value,log_index=value,log_count=value,log_size=value,parse_header,parse_log_footer,parse_block_bitmap,parse_blk2off_table,parse_block_state_area,parse_maptbl_cache,parse_all,raw_dump. yeah bestie, that's a whole lot of keywords, and every single one of them is literally written right there in the syntax above. pick your fighters. 🧚
  • -q, --quiet — Quiet execution (useful for scripts). no yapping, just output. 🤫
  • -r, --raw-dump _show,offset=value,size=value_ — Show raw dump from specified offset and size. straight-up bytes, no parsing, no commentary. 💜
  • -V, --version — Print version and exit. for when you just gotta know. ⭐

🌈 MODES OF OPERATION 🌈

dump.ssdfs operates in several modes:

Granularity mode (default)

Shows key volume details including superblock information, geometry, and overall file system structure. the "big picture" girlie. ✨

PEB dump mode

Dumps Physical Erase Block (PEB) content with various parsing options for headers, footers, bitmaps, and mapping tables. the "zoom in on one block and take it apart" mode. 🔬

Raw dump mode

Extracts raw binary data from specified offset and size. just. raw. bytes. 💀

🫶 EXIT STATUS 🫶

dump.ssdfs exits with status 0 on success, or with non-zero status on error.

translation: 0 = slay, anything else = something went wrong, go read the error. 😭

💖 EXAMPLES 💖

Show key volume details (default):

# dump.ssdfs /dev/sdb1

Dump first PEB with header parsing:

# dump.ssdfs -p id=0,parse_header /dev/sdb1

Extract raw data from specific offset:

# dump.ssdfs -r show,offset=1024,size=4096 /dev/sdb1

Dump PEB content to files in specific folder:

# dump.ssdfs -o /tmp/ssdfs_dump -p id=0,parse_all /dev/sdb1

copy these exactly, they are literally the recipes. do not freestyle the commas. 🎀
