This project implements a program called pipex that simulates the behavior of the shell command < file1 cmd1 | cmd2 > file2. It takes four arguments: file1, cmd1, cmd2, and file2, where file1 and file2 are file names, and cmd1 and cmd2 are shell commands with their respective parameters.

The program must be executed as follows:

./pipex file1 cmd1 cmd2 file2

$> ./pipex infile "ls -l" "wc -l" outfile

Should be identical to < infile ls -l | wc -l > outfile.

$> ./pipex infile "grep a1" "wc -w" outfile

Should be identical to < infile grep a1 | wc -w > outfile.

• Input/output handling with files and pipes.
• Execution of specified shell commands with their parameters.
• Sensible error handling to avoid unexpected interruptions.
• No memory leaks.
• Multiple pipe handling for bonus points.

The main function that directs the program flow by checking for errors, determining whether to execute the rescue command, and calling the appropriate functions.

Chooses the child or parent process to execute based on the PID returned by the fork function.

Creates a new child process to execute a command.

Implements the bonus functionality for handling multiple pipes.

• Multiple pipe handling.
• Project validated at 115%.

The project is compiled using a Makefile that compiles the source files without relinking.

The project can be compiled using the following Makefile rules:

• make or make all: Compiles the main project.
• make bonus: Compiles the project with bonus features.
• make clean: Removes object files and compilation folders.
• make fclean: Removes object files, compilation folders, and the executable.
• make re: Performs a complete reset of the project by removing all generated files and recompiling everything from scratch.

• Error handling without unexpected interruptions.
• No memory leaks.
