execve

Tracer for execve{,at} and pre-exec behavior, launcher for debuggers.

ulexecve is a userland execve() implementation which helps you execute arbitrary ELF binaries on Linux from userland without the binaries ever having to touch storage. This is useful for red-teaming and anti-forensics purposes.

Advanced process execution monitoring utility for linux (procmon like)

An implementation of execve() in user space

A Ruby micro-framework for writing and running exploit payloads

pipex is a 42 school project aimed to better understand shell redirection and pipes, by handling them in C.

The goal of this project is to create a simple shell. Will be your own little bash or zsh. You are going to learn a lot about processes and file descriptors.

handling pipes in C language

🏆 Minishell Project is a 42 project that recreates a simplified version of Bash. It handles command execution, input/output redirection, and environment variables, offering a deeper understanding of shell internals and process management.

A CGI program that finds leaked file descriptors and actively exploits them: connection hijacking, epoll exhaustion, directory corruption, and more

For multithreaded programs that fork(2)!

42cursus-Pipex: C program that recreates the functionality of shell pipes (|) and HereDoc (<< Del). This project focuses on inter-process communication by using fork(), pipe(), dup2(), and execve() to redirect the output of one command to the input of another, mimicking the shell command < infile cmd1 | cmd2 > outfile.

A recreation of Bash's core behavior from scratch — parsing, pipes, redirections, heredocs, environment variables, and built-in commands (cd, echo, export, unset, pwd, env, exit) — using the Readline library for input and matching Bash's real exit-code behavior. Team project.

It is an imitation of the Unix shell built in the C language

As beautiful as a shell

A C implementation of the UNIX pipe mechanism that replicates the behavior of shell command piping. This project provides hands-on experience with process management, file descriptors, and inter-process communication in UNIX-like systems.

Creating a basic shell from scratch

creating a mini shell that mimic the behavior of bash

A lightweight, reduced version of the Bash shell written in C.

C program that replicates the shell's pipe functionality. It reads input from a file, executes two commands and directs the output to another file.
