OBJECT-REWRITE(1)

💅 OBJECT-REWRITE 💅

okay bestie, so object-rewrite lives in the User Commands section of the manual (section 1, obvs) and it's literally here to rewrite your object files with whatever modifications you're feeling. no cap. ✨

---

🌸 NAME 🌸

object-rewrite — rewrite object files with modifications 🦋

---

✨ SYNOPSIS ✨

object-rewrite [OPTIONS] <input> [output]

---

🎀 DESCRIPTION 🎀

Rewrite object files with modifications. that's it, that's the whole vibe. you feed it an object file, you tell it what to change, it hands you a new one. iconic behavior honestly. 💖

🫶 Arguments:

• <input> — the input file. the one you're reading from, the main character. 👑
• [output] — the output file. required if any modification is requested, so if you're out here asking for changes and you forgot the output, that's on you bestie 😭

---

🔥 OPTIONS 🔥

• --delete-symbol <symbol> — delete the named symbol. gone. poof. bye. 💀
• --rename-symbol <old=new> — change the name of a symbol from <old> to <new>. glow-up for a symbol, fr fr.
• --rename-symbols <file> — read a list of symbol names from <file> and apply --rename-symbol for each one. each line contains two symbols separated by whitespace. batch rename, we love a mass glow-up ✨
• --delete-section <section> — delete the named section. whole section? deleted. not me being ruthless 🙈
• --rename-section <old=new> — change the name of a section from <old> to <new>.
• --elf-add-dynamic-debug — add a DT_DEBUG entry to the dynamic section.
• --elf-print-runpath — print any DT_RPATH or DT_RUNPATH entries in the dynamic section.
• --elf-delete-runpath — delete any DT_RPATH and DT_RUNPATH entries in the dynamic section.
• --elf-set-runpath <path> — set the path for any DT_RPATH or DT_RUNPATH entry in the dynamic section.
• --elf-add-runpath <path> — add a path to any DT_RPATH or DT_RUNPATH entry in the dynamic section.
• --elf-use-rpath — change any DT_RUNPATH entry in the dynamic section to DT_RPATH.
• --elf-use-runpath — change any DT_RPATH entry in the dynamic section to DT_RUNPATH. yes it's the reverse of the one above, they're sisters, don't @ me 💅
• --elf-print-needed — print the DT_NEEDED entries in the dynamic section.
• --elf-delete-needed <name> — delete the named DT_NEEDED entry in the dynamic section.
• --elf-replace-needed <old=new> — change the value of a DT_NEEDED entry from <old> to <new>.
• --elf-add-needed <name> — add a DT_NEEDED entry to the start of the dynamic section. not the end, bestie. the start. read it again 👀
• --elf-print-soname — print the DT_SONAME entry in the dynamic section.
• --elf-set-soname <name> — set the DT_SONAME entry in the dynamic section.
• --elf-print-interpreter — print the interpreter path in the PT_INTERP segment.
• --elf-set-interpreter <path> — set the interpreter path in the PT_INTERP segment.
• --ignore-unknown-format — ignore input files with unknown formats. "i don't know her" energy, but for file formats 🫶
• -v, --verbose — enable verbose output. she talks more. we listen. 🎧
• -h, --help — print help.
• -V, --version — print version.

also psst: every single one of those --elf-* flags is ELF-specific, so if your object file isn't ELF, don't be surprised when things get weird. iykyk 🌈
