💖 llvm-otool(1) — the Mach-O dumping tool, bestie edition 💖

okay so. you found the llvm-otool manual page and honestly? you're about to have a great time. this is a page from the LLVM manual collection, and it's all about poking at Mach-O files like the absolute detective you are 🕵️♀️✨

🌸 NAME 🌸

llvm-otool — Mach-O dumping tool. that's it. that's the whole name. iconic, minimal, no notes. 💅

🦋 SYNOPSIS 🦋

llvm-otool [option…] [file…]

options, files, go. very "we contain multitudes" of it.

🎀 DESCRIPTION 🎀

so llvm-otool is a tool for dumping Mach-O files. Mach-O files are like… the little nested-onion situation macOS uses, and this thing unpeels them for you. 🧅

and the real tea? it attempts to be command-line-compatible and output-compatible with macOS's otool. so if you already know otool, you already lowkey know this. slay. 🔥

✨ OPTIONS ✨

one bullet per flag, no skips, no shortcuts, because we do not leave the boring ones out in this house. 👑

  • -arch <value> — pick a slice out of a universal Mach-O file. universal files are giving "many selves in one body" and this chooses which one you're talking to. 🌈
  • -chained_fixups — print the chained fixup information. fixups! but chained! 🔗
  • -C — print linker optimization hints. little helpful whispers from the linker. 💬
  • -dyld_info — print bind and rebase information. dyld's whole deal, laid bare. 🫶
  • -D — print the shared library id. who are you, library? 💅
  • -d — print the data section. the data. the vibes. 🍓
  • -f — print universal headers. the headers up top, but make them universal. 🌍
  • -G — print the data-in-code table. yes bestie, it's a table. 📋
  • --help-hidden — print help for hidden flags. the secret menu. the lore. 👀
  • --help — print help. the regular, non-secret menu. 🎀
  • -h — print mach header. lowercase h, capital importance. ⭐
  • -I — print the indirect symbol table. indirect! like a situationship, but for symbols. 😭
  • -j — print opcode bytes. raw little bytes, unfiltered. 💀
  • -L — print used shared libraries. the library guest list. 💜
  • -l — print load commands. (lowercase L, yes, careful — -I and -l are different and they will humble you.) 🧚
  • -mcpu=<value> — select cpu for disassembly. tell it which brain to use. 🧠
  • -o — print the Objective-C segment. the Obj-C corner of the world. 🌸
  • -P — print the __TEXT,__info_plist section as strings. plist but make it strings. ✨
  • -p <function name> — start disassembly at <function name>. jump straight to your fave function, main character behavior. 👑
  • -r — print relocation entries. everything moves, nothing stays. 🦋
  • -s <segname> <sectname> — print contents of a section. two args, segment then section, in that order, don't flip them bestie. 🙈
  • -t — print the text section. the text. the classics. 📖
  • --version — print version. because sometimes you just need to know. 💖
  • -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. loud and proud, and it disassembles for you when you're printing text sections. 📣
  • -X — omit leading addresses or headers. minimalism era. clean lines, no clutter. 🎀
  • -x — print all text sections. all of them. every last one. no crumbs. 🔥
  • @<FILE> — read command-line options and commands from response file <FILE>. a file full of options? she's organized, she's efficient, she ate. 💅

🌈 EXIT STATUS 🌈

okay so here's the vibe check:

  • if there's an error, llvm-otool exits with a non-zero exit code. 🚨
  • otherwise, it exits with code 0. we love a clean exit. 💚
