🦋 LLVM-OTOOL — the Mach-O dumping tool, bestie edition

okay so real quick, before we get into it: this is the llvm-otool manual page, from the LLVM crew (that's the manual name right up at the top, iykyk 💅). She's a whole vibe and she's here to spill everything about your Mach-O files. Let's go ✨

🎀 SYNOPSIS

llvm-otool [option…] [file…]

💖 DESCRIPTION

llvm-otool is, at her core, a tool for dumping Mach-O files. That's the assignment, that's the whole job, and she does it iconically.

The way that she's built? She literally attempts to be command-line-compatible and output-compatible with macOS's otool. So if you know otool, you already know her. Same energy, same output, no cap. 🫶

✨ OPTIONS ✨

okay this is the good part, the whole flag buffet. Every single one, no skipping, because we don't gatekeep here:

  • -arch <value> — select the slice of a universal Mach-O file. universal = multiple archs in one file, and this is how you pick your main character 🎀
  • -C — print linker optimization hints.
  • -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 the hidden flags. the secret menu, lowkey 👀
  • --help — print help. the regular menu.
  • -h — print the mach header.
  • -I — print the indirect symbol table.
  • -j — print opcode bytes.
  • -L — print the used shared libraries.
  • -l — print load commands (the manpage literally spells it commnads, and honestly? same 💀 keeping it real).
  • -mcpu=<value> — select the cpu for disassembly.
  • -o — print the Objective-C segment.
  • -P — print the __TEXT,__info_plist section as strings. plist girlies rise 🌸
  • -p <function name> — start disassembly at <function name>. like dropping a pin and saying "start here bestie"
  • -r — print relocation entries.
  • -s <segname> <sectname> — print the contents of a section. you give her the segment name and the section name, both, no shortcuts ✨
  • -t — print the text section.
  • --version — print the version.
  • -V — symbolize disassembled operands. heads up: this implies -v, she comes as a package deal 💜
  • -v — verbose output, and also disassemble when printing text sections. she's doing double duty and she ate 🔥
  • -X — omit leading addresses or headers.
  • -x — print all text sections.
  • @<FILE> — read command-line options and commands from the response file <FILE>. yes, a file full of flags, iconic behavior 👑

🫶 EXIT STATUS

llvm-otool exits with a non-zero exit code if there's an error. Otherwise? She exits with code 0. Clean, tidy, slay. ⭐
