pipex is a 42 school project designed to understand shell redirections and pipes by building them in C. Parent-children processes communication is done by leveraging the shared nature (between processes) of file descriptors to the open file table.

This pipex program takes an input file, execute a command on it, pipes the result to another command which then writes its result to an output file.

The result should mimic exactly the shell command:

$ < input_file command1 | command2 > output file

this include error exit code and messages for every cases.

It is built using the following system functions and system calls open, close, read, write, dup2, execve, fork, pipe, waitpid

Grade: 100%

Compile with make

Pipex can handle 2 commands :

./pipex input_file command1 command2 output_file

this will execute the same as the following shell command :

$ < input_file command1 | command2 > output_file

You could test with an input_file containing "Go dance salsa somewhere Christina :)”
