DUMP.F2FS(8)

okay bestie, this is the dump.f2fs page from the System Manager's Manual — yes, the DUMP.F2FS(8) one — and we're keeping the whole lore intact 💖

💖 NAME 💖

dump.f2fs — retrieve directory and file entries from an F2FS-formated image. Yes, F2FS-formated is the original spelling and we are not fixing it, periodt ✨

🦋 SYNOPSIS 🦋

okay so the group-chat invocation is literally:

dump.f2fs [ -i inode number ] [ -I inode number ] [ -n NAT range ] [ -M Block map ] [ -s SIT range ] [ -a SSA range ] [ -b block address ] [ -d debugging-level ] device

🌸 DESCRIPTION 🌸

dump.f2fs is used to retrieve f2fs metadata (usually in a disk partition). device is the special file corresponding to the device (e.g. /dev/sdXX). No cap.

Currently, it can retrieve:

1. a file or folder given its inode number (folders are dumped recursively)
2. NAT entries into a file
3. SIT entries into a file
4. SSA entries into a file
5. reverse information from the given block address

The exit code returned by dump.f2fs is 0 on success and -1 on failure. That's the vibe check: success = 0, failure = -1 💀

✨ OPTIONS ✨

• -i inode number — specify an inode number to dump out. Slay.
• -r — dump out from the root inode. Starting at the root is very main-character energy 🌱
• -f — do not prompt before dumping. Less "are you sure?" more "go go go" 💅
• -y — alias for -f. Same energy, different letter.
• -o path — dump inodes to the given path.
• -P — preserve mode/owner/group for dumped inode. Keep the whole fit intact 👑
• -L — preserves symlinks. Otherwise symlinks are dumped as regular files. Choose your fighter 🦋
• -I inode number — specify an inode number and scan full disk to dump out, include history inode block. Full-scan behavior, bestie.
• -n NAT range — specify a range presented by nids to dump NAT entries. NAT range realness.
• -M Block map — show all the allocated block addresses given inode number.
• -s SIT range — specify a range presented by segment numbers to dump SIT entries.
• -a SSA range — specify a range presented by segment numbers to dump SSA entries.
• -b block address — specify a block address to retrieve its metadata information.
• -d debug-level — specify the level of debugging options. The default number is 0, which shows basic debugging messages.
• -N — answer "No" for all questsions — yes, that spelling is from the original, and I'm keeping the artifact 😭

and that's the whole entire page, bestie — System Manager's Manual energy, footer just says DUMP.F2FS(8), and this copy doesn't give us a separate source/version/date line, so I'm not inventing one. periodt 💅🎀
