  🇺🇸 Pipex is the sixty project at 42. This project will let you discover in detail a UNIX mechanism that you already know by using it in your program. The aim of the project is reproduce the behavior of pipe.

  🇧🇷 Pipex é o sexto projeta da 42. Este projeto permitirá que você descubra em detalhes um mecanismo UNIX que você já conhece usando-o em seu programa. O objetivo do projeto é reproduzir o comportamento do pipe.

We need to implement the following rules:

• Your program will be executed as follows:

./pipex file1 cmd1 cmd2 file2  

• It must take 4 arguments:
file1 and file2 are file names.
cmd1 and cmd2 are shell commands with their parameters

• You have to turn in a Makefile which will compile your source files. It must not relink.

• You have to handle errors thoroughly. In no way your program should quit unexpectedly (segmentation fault, bus error, double free, and so forth).

• Your program mustn’t have memory leaks.

• If you have any doubt, handle the errors like the shell command:

< file1 cmd1 | cmd2 > file2  

📝 Files

Name	Description
pipex.h	The header with functions libraries and prototypes.
pipex.c	Contains 3 functions to handle with fork and commands.
main.c	Contains the main and the function to initialize de struct.
utils.c	Contains the fuctions to handle with file and get the path.
error.c	Contains the functions who deal with errors.
Makefile	The automatizated compilator.

🛠️ Usage

Then you can run this commands below

$> make
$> ./pipex infile cmd1 cmd2 outfile

• infile: a file to get data
• cmd1 and cmd2: shell commands, if the commands have flags, you need to use like this "cmd -flag"
• outfile: a file to output the result
