Pipex is an exciting coding project that emulates the behavior of the Unix pipe command (|) in C. It showcases efficient use of file descriptors, process creation with fork, and inter-process communication with Unix pipes.

• Unix Pipe Emulation: Mimics the behavior of Unix pipes to connect commands.
• Process Management: Utilizes fork to create child processes for command execution.
• Error Handling: Robust error handling for a seamless user experience.
• File Descriptor Management: Efficient handling of file I/O operations.

The project reads commands from the command line, creates a pipeline of processes, and connects their input and output streams accordingly. It primarily involves creating two processes using fork, where one process handles the input and the other handles the output.

• cmdline_parser.c: Parses command line arguments and validates their count.
• error_handling.c: Contains functions for error reporting and handling.
• file_handling.c: Manages file operations like opening, checking permissions, etc.
• pipe_creation.c: Handles the creation and management of pipes between processes.
• pipex_bonus.c: Implements the bonus part, handling multiple pipes and the "here_doc" feature.
• pipex_utils_bonus.c: Utility functions for the bonus part, including file opening and usage instructions.
• pipex_utils.c: Utility functions for finding executable paths and executing commands.
• pipex.c: The main function that orchestrates the flow of the program.

1. Clone the Repository:

   git clone https://github.com/rogalio/Pipex

2. Compile the Project:

   make

   This will compile the pipex program.

Execute the program with the following syntax: ./pipex file1 cmd1 cmd2 file2 Where file1 and file2 are filenames, and cmd1 and cmd2 are Unix commands.

Pipex demonstrates inter-process communication using Unix pipes. It involves concepts like file descriptors, fork for process creation, and execve for executing commands. Error handling and file permissions are key aspects of its robust design.
