Features

• Simulates the behavior of the shell pipe (|) with two commands.
• Supports input and output redirection.
• Works on Unix-like systems.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Your system should be running a Unix-like operating system (e.g., Linux or macOS).
• You should have a C compiler (e.g., GCC) installed on your system.

Installation

Usage

./pipex file1 cmd1 cmd2 file2

file1: Input file whose content will be passed as input to cmd1.
cmd1: The first command to run.
cmd2: The second command to run.
file2: Output file where the result will be stored.

Examples

Example 1: Using a simple pipe

./pipex infile "ls -l" "grep keyword" outfile

./pipex infile "cat" "sort -r" > outfile

Example 3: Using command substitution

./pipex infile "$(cat filelist)" "grep pattern" outfile
