It started out as a way to simplify the hassle of changing libc back and forth when doing pwn topics, and to simplify the commands, got a little script that can be added to /usr/local/bin as a shortcut command 🔢
This is written in the tools repository (git clone /CH13hh/), so feel free to download it and suggest some optimizations if you need them.

Installation
git clone /CH13hh/
cd
sudo chmod +x patlibc
sudo cp patlibc /usr/local/binIt is ready to use after completing the above steps.

Usage: patlibc <new_libc_path> <new_ld_path> <lib_name> <pwn_name>
eg: patlibc ./.6 ./.6 .6 ./pwnMethod 2: Three-parameter model(For use withglibc-all-in-one to replacelibc (library)
