LLVM-OTOOL(1)

💅 LLVM-OTOOL(1) — the llvm-otool page, but make it make sense

okay so real quick: this is a page from the LLVM manual set, and it's about llvm-otool, which literally dumps Mach-O files. bestie, if you've ever stared at a macOS binary like "what is in you", this is the tool. 🦋

✨ NAME ✨

llvm-otool — the Mach-O dumping tool. that's it, that's the vibe. it dumps Mach-O files. 👑

🌸 SYNOPSIS 🌸

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

💖 DESCRIPTION 💖

So llvm-otool is a tool for dumping Mach-O files. 🎀

And here's the slay part: it attempts to be command-line-compatible and output-compatible with macOS's otool. like, it's giving "drop-in replacement" energy. no cap. ✨

🧚 OPTIONS 🧚

okay this is the long part, grab a snack 🍓 — every single one, in order, nothing skipped, periodt:

• -a — print the archive header.
• -arch <value> — pick which slice of a universal Mach-O file you want.
• -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 the hidden flags 👀 (iykyk).
• --help — print help.
• -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.
• -m — don't use the archive(member) syntax.
• -mcpu=<value> — select the 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 the contents of a section. two args, bestie, don't forget the second one 😭
• -t — print the text section.
• --version — print version.
• -V — symbolize disassembled operands. implies -v, so you get verbose whether you asked or not 💅
• -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 the 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. clean, simple, iconic. ✨
