infile: the input file to be read and piped into the first command.
cmd1: the first command to be executed.
cmd2: the second command to be executed.
outfile: the output file where the result of the pipeline will be written.
The program executes the command pipelinecmd1 | cmd2 and redirects the input and output accordingly, similar to the behavior of the shell command| (pipe).
Projects Components Table
This is an overview of the main components located in the "sources" directory of the 42_pipex project.
File/Header File
Description
libft
A directory containing the Libft library, used for auxiliary functions required for the implementation of pipex.
Makefile
The Makefile script for automating project compilation. It includes rules for compiling pipex and additional rules for project management.
sources/pipex.c
The main file containing the pipex function, responsible for executing the command pipeline and file redirection.
sources/utils.c
Contains utility functions used by the pipex program for tasks such as string manipulation and error handling.
sources/pipex.h
The header file containing function prototypes and macro declarations necessary for using the pipex program.
Usage
To use thepipex program, compile it using the provided Makefile. Then, run the program with the required arguments:
./pipex infile"cmd1""cmd2" outfile
Features
42_pipex offers the following features:
Command Pipeline Simulation: Executes the command pipelinecmd1 | cmd2 to simulate the behavior of shell pipes.
File Redirection: Redirects input and output files as specified by the user to facilitate the execution of the command pipeline.
Error Handling: Properly handles errors and returns appropriate exit codes in case of failure.
About
This project is part of the curriculum at Ecole 42. "42_pipex" is a program that simulates the functionality of the shell command pipeline.
