pipex

Reimplementation of UNIX pipes behavior in C.

📖 Description

The pipex project consists of recreating the behavior of UNIX pipes (|) in C.

It executes a series of commands, redirecting the output of one command as the input of the next.

To achieve this, pipex makes use of:

• "File descriptors for redirection"
• "Pipes for inter-process communication"
• "fork() and execve() for process creation and command execution"

🛠️ Features

• Handle two-command piping (mandatory part)
• Extend to multiple commands (bonus)
• Support here_doc functionality with a limiter (bonus)
• Correctly manage file redirections (<, >, >>)
• Robust handling of processes and errors
