CTF_INSERT(1)

💖 CTF_INSERT(1) 💖

okay so this page is from the General Commands Manual, bestie, and it's giving “insert CTF data into a mach_kernel file” main character energy. No cap, let’s get into it. 💅✨

🌸 NAME 🌸

ctf_insert — insert Compact C Type Format data into a mach_kernel file. 🎀

✨ SYNOPSIS ✨

ctf_insert input [ -arch arch file ]... -o output

🦋 DESCRIPTION 🦋

ctf_insert inserts CTF (Compact C Type Format) data into a mach_kernel binary, and it stores that data in a newly created (__CTF,__ctf) section. The way this tool just makes a whole new section? Iconic. ✨

🚨 vibe check, bestie: this (__CTF,__ctf) section must not be present in the input file. Like, it cannot already be there. Not me warning you dramatically, but fr fr — do not pass an input that already has it. 💀

ctf_insert(1) must be passed one -arch argument for each architecture in a universal file, or exactly one -arch for a thin file. That part is strict, okay? 👑

• input — specifies the input mach_kernel. 🍓
• -o output — specifies the output file. 💾
• -arch arch file — specifies a file of CTF data to be used for the specified arch in a Mach-O or universal file. The file’s content will be stored in a newly created (__CTF,__ctf) section. 🦋
