CC-Uniq - Command-Line Unique Line Processor

This project is a custom implementation of the classic Unix uniq command. It was developed as part of a coding challenge here. The utility is designed to filter and manipulate duplicate lines from input data, providing detailed control over the output displayed.

Features

• Filter out duplicate lines or exclusively show them.
• Count the occurrences of each line.
• Output results to standard output or a specified file.
• Handle input from both files and standard input (piping).
• Efficiently process large text data.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• You need to have Go installed on your machine (Go 1.15 or later is recommended).
• You can download and install Go from https://golang.org/dl/.

Installing

Clone the repository to your local machine:

git clone https://github.com/nullsploit01/cc-uniq.git
cd cc-uniq

Building

Compile the project using:

go build -o ccuniq

Usage

To run the utility, you can either pass a file name as an argument or pipe text into it via standard input.

Print unique lines from a file:

./ccuniq -u filename.txt

Print only repeated lines:

./ccuniq -d filename.txt

Count occurrences of each line in a file:

./ccuniq -c filename.txt

Using piped input to filter unique lines:

cat filename.txt | ./ccuniq -u

Running the Tests
