LLVM-OTOOL(1)

💅 LLVM-OTOOL (like, the Mach-O dumping tool bestie)

okay so real quick before we dive in — this whole page is from the LLVM manual suite, section 1. that's the vibe. ✨

🌸 NAME

llvm-otool — a Mach-O dumping tool. literally what it says on the tin, no cap.

🎀 SYNOPSIS

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

🦋 DESCRIPTION

so llvm-otool is a tool for dumping Mach-O files. that's the whole assignment 💅

and here's the slay part: it attempts to be command-line-compatible and output-compatible with macOS's otool. like, it's giving "i can sit at the same table as the original." 🫶

✨ OPTIONS ✨

okay buckle up, there's a lot, but every single one is here so don't skip:

• -arch <value> — picks which slice of a universal Mach-O file you wanna look at. universal files are like a little friend group of architectures, and this is you choosing who to talk to 🎀
• -chained_fixups — prints chained fixup information. fancy internal stuff, very demure ✨
• -C — prints linker optimization hints.
• -dyld_info — prints bind and rebase information. dyld said "let me explain myself" 😭
• -D — prints the shared library id.
• -d — prints the data section.
• -f — prints universal headers.
• -G — prints the data-in-code table.
• --help-hidden — prints help for the hidden flags. yeah there's a secret menu 💀
• --help — prints help. the normal menu, no secrets.
• -h — prints the mach header.
• -I — prints the indirect symbol table.
• -j — prints opcode bytes.
• -L — prints the used shared libraries.
• -l — prints load commands. lowercase L, uppercase vibes 👑
• -mcpu=<value> — selects the cpu for disassembly. yes, you tell it which brain to use 🧠
• -o — prints the Objective-C segment.
• -P — prints the __TEXT,__info_plist section as strings. plist info but make it readable 🍓
• -p <function name> — starts disassembly at <function name>. like dropping a pin 📍
• -r — prints relocation entries.
• -s <segname> <sectname> — prints the contents of a section. you give it a segment name and a section name, both, don't be shy 🫶
• -t — prints the text section.
• --version — prints the version. hi what's your sign, it's --version 💅
• -V — symbolizes disassembled operands (and yes, this implies -v — it comes with a plus-one, iconic 💖)
• -v — verbose output / disassemble when printing text sections. it's giving "tell me everything" 😭
• -X — omits leading addresses or headers. minimalism era 🎀
• -x — prints all text sections. all of them. the whole timeline.
• @<FILE> — reads command-line options and commands from the response file <FILE>. it's like a little note you pass to your bestie instead of shouting every flag out loud 📝

💀 EXIT STATUS

llvm-otool exits with a non-zero exit code if there is an error. otherwise, it exits with code 0. so like — 0 means we're good, anything else means something went sideways. periodt. 🦋

🙈 BUGS

gotta report a bug? be my guest, go here:

(the original page breaks that URL across a line with a hyphen — it's one URL, promise 🫶)
