Pipex is a project commonly assigned in the curriculum of the 42 coding school. Its main objective is to introduce students to UNIX pipes and inter-process communication. In Pipex, you re-create in C the shell's pipeline operator (`|`), which allows the output of one command to be used as the input for another command.

A library of useful C functions

A C function that reads any valid file line by line - @42sp Project

File descriptor passing through UNIX socket

get_next_line (GNL): project focused on file I/O and memory management. The task is to write a single function, get_next_line, that reads from a file descriptor and returns one line at a time. This project requires careful handling of static variables, buffer management, and reading data in chunks to efficiently process files of any size.

Capture stdout, stderr, and other file descriptors of running processes on-the-fly, without redirects, screen, or tmux.

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.

Write data to any file descriptor in any processs.

This function reads from a file descriptor and returns a single line at a time. It’s designed to handle any file or standard input efficiently, making it easy to process text line by line.
