💖 FSAPFSINFO(1) 💖

okay bestie, so this is the fsapfsinfo manual page — it lives in the LOCAL section of your man pages, and it's genuinely one of my faves. pull up a chair, grab a boba, and let's get into it 🧋✨

✨ NAME ✨

fsapfsinfo — tells you everything about an Apple File System (APFS). like, everything. it's giving detective energy 🔍👑

---

🦋 SYNOPSIS 🦋

fsapfsinfo [-B bodyfile] [-E identifier] [-f file_system_index]
           [-F path] [-o offset] [-p password] [-r password] [-dhHvV]
           source

🌸 DESCRIPTION 🌸

fsapfsinfo is a utility that determines information about an Apple File System (APFS). yes, the whole thing. she's nosy and we love her for it 💅

fsapfsinfo is part of the libfsapfs package. libfsapfs is a library to access the Apple File System (APFS) format. so basically, if APFS is the main character, libfsapfs is the bestie holding her purse 🫶

source is the source file. that's the thing you're pointing her at, bestie. don't forget it.

the options are as follows, and no we are NOT skipping any of them:

• -B bodyfile — output file system information as a bodyfile. slay, now it's in bodyfile format.
• -d — calculate a MD5 hash of a file entry to include in the bodyfile. hashes? in my bodyfile? more likely than you think ✨
• -E identifier — show information about a specific file system entry, or just say "all" if you want the whole squad.
• -f file_system_index — show information about a specific file system, or "all" for every single one. no cap.
• -F path — show information about a specific file entry path. just point her at a path and she'll spill the tea.
• -h — shows this help. hi bestie, this is your lifeline 🙈
• -H — shows the file system hierarchy. the whole family tree, iconic.
• -o offset — specify the volume offset. important for when your image isn't starting at zero, iykyk.
• -p password — specify the password. shhh, don't tell anyone 🤫
• -r password — specify the recovery password. for when regular password said no and you need the backup queen to step in 👑
• -v — verbose output to stderr. she gets chatty.
• -V — print version. the classic.

🔥 EXAMPLES 🔥

okay so here's the moment you've all been waiting for, the demonstration:

# fsapfsinfo -o 20480 image.dmg
fsapfsinfo 20220728

Apple File System (APFS) information:

Container information:
        Identifier                      : d08a9fa0-d5a5-458b-813e-ebf9bf5d5338
        Number of volumes               : 1

Volume: 1 information:
        Identifier                      : 458ed10d-8ac3-4af1-8dfd-3954d151a3f3
        Name                            : apfs_test
        Compatible features             : 0x00000002
                (NX_FEATURE_LCFD)

        Incompatible features           : 0x00000001
                (NX_INCOMPAT_VERSION1)

        Read-only compatible features   : 0x00000000

        Number of snapshots             : 0

look at that output. gorgeous. pristine. the container identifiers, the volume name apfs_test, all those feature hex values, the snapshot count. ate and left no crumbs 💅✨

---

⭐ DIAGNOSTICS ⭐

errors, verbose and debug output are printed to stderr when verbose output -v is enabled. quick heads up though: verbose and debug output are only printed when enabled at compilation. so if you compile without it and turn on -v and get nothing, that's not a bug bestie, that's the build 😭
