Pipex

Pipex reproduces the behavior of shell piping (|), executing a chain of commands with input/output redirection using pipe(), fork(), execve(), and dup2().

Usage

Cloning the Repository

To get started with the project, clone the repository to your local machine:

git clone https://github.com/droubarka/pipex.git

Running the Program

cd ./pipex
make bonus

Basic Usage

./pipex infile "cmd1" "cmd2" ... "cmdN" outfile

Equivalent to the shell command:

< infile cmd1 | cmd2 | ... | cmdN > outfile

Example:

./pipex /etc/passwd "grep -P [\w/]*/nologin$" "cut -d: -f1" nologin.txt

• Extracts users with /nologin shells and writes their usernames to nologin.txt.

Here Document Mode (Interactive Input)

./pipex here_doc LIMITER "cmd1" "cmd2" outfile

• Reads from standard input until LIMITER is encountered, then pipes through the commands.
