LLVM-OTOOL(1)

💖 llvm-otool — the Mach-O tea spiller 💖

okay bestie, welcome to llvm-otool, from the LLVM manual collection ✨ (section 1, the "user commands" corner of the universe, iykyk). it's a Mach-O dumping tool, and it's about to tell you absolutely everything about your binary. no secrets. no cap. 🫶

---

✨ SYNOPSIS ✨

llvm-otool [option...] [file...]

give it some options, give it some files, and watch it spill. 💅

---

🌸 DESCRIPTION 🌸

so basically llvm-otool is a tool for dumping Mach-O files. that's the whole vibe. 🦋

and here's the iconic part: it attempts to be command-line-compatible and output-compatible with macOS's otool. so if you're switching over, your scripts and your muscle memory both get to stay. periodt. 👑

🎀 OPTIONS 🎀

one bullet per flag, exactly as they come, no notes skipped:

• -arch <value> — pick a slice of a universal Mach-O file. universal binaries are giving ✨options✨ and this is how you choose one.
• -chained_fixups — print chained fixup information.
• -C — print linker optimization hints.
• -dyld_info — print bind and rebase information.
• -D — print the shared library id.
• -d — print the data section.
• -f — print universal headers.
• -G — print the data-in-code table.
• --help-hidden — print help for hidden flags. 👀 the secret menu.
• --help — print help. the normal, non-secret menu.
• -h — print mach header.
• -I — print indirect symbol table.
• -j — print opcode bytes.
• -L — print used shared libraries.
• -l — print load commands.
• -mcpu=<value> — select cpu for disassembly.
• -o — print the Objective-C segment.
• -P — print the __TEXT,__info_plist section as strings.
• -p <function name> — start disassembly at <function name>.
• -r — print relocation entries.
• -s <segname> <sectname> — print contents of section. two placeholders, bestie, don't forget the second one 🫶
• -t — print text section.
• --version — print version.
• -V — symbolize disassembled operands (implies -v). yes it drags -v along with it, they're a package deal 💜
• -v — verbose output / disassemble when printing text sections.
• -X — omit leading addresses or headers.
• -x — print all text sections.
• @<FILE> — read command-line options and commands from response file <FILE>.

🔥 EXIT STATUS 🔥

llvm-otool exits with a non-zero exit code if there is an error. otherwise, it exits with code 0.

translation: 0 means we ate, non-zero means something went sideways 😭
