The pipex
program takes four arguments:
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 pipeline cmd1 | cmd2
and redirects the input and output accordingly, similar to the behavior of the shell command |
(pipe).
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. |
To use the pipex
program, compile it using the provided Makefile. Then, run the program with the required arguments:
./pipex infile "cmd1" "cmd2" outfile
42_pipex offers the following features:
-
Command Pipeline Simulation: Executes the command pipeline
cmd1 | 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.
