🚀 cc - Ultimate, Ultra-Optimized Cat Replacement

---

🌟 Overview

cc is an ultra-optimized, resource-efficient replacement for the classic Unix cat command. Designed with performance in mind, cc provides enhanced text processing capabilities and additional features that experienced developers have long desired, such as follow mode for real-time file updates.

Whether you need to quickly concatenate files or monitor log files in real time, cc delivers high speed, minimal CPU and memory usage, and a suite of options to tailor its behavior to your workflow.

Note: This project is solely a personal experiment by itlwas and is not intended for continuous development. It serves as a proof-of-concept rather than a fully evolving product.

✨ Features

• Fast Raw Output: Directly output file content with minimal overhead.
• Enhanced Text Formatting:
  • Line Numbering: Number all lines (-n) or only nonblank lines (-b).
  • Blank Line Squeezing: Suppress repeated blank lines (-s).
  • End-of-Line Markers: Append markers at the end of each line (-e).
  • Tab Visualization: Display TAB characters as ^I (-T).
  • Nonprinting Characters: Convert nonprinting characters to a readable format (-v).
  • Combined Flag: -A is equivalent to -v -T -e.
• Follow Mode: Continuously output appended data in real time (similar to tail -f) with the -f flag.
• Memory Mapping: Uses memory mapping for files larger than 1MB to minimize data copying and boost performance.
• Optimized Resource Usage: Minimal allocations and efficient data processing for extremely large files.

📖 Usage

Basic Examples

• Concatenate and Display a File:

  ./cc file.txt

• Display a File with Line Numbers and Squeeze Blank Lines:

  ./cc -n -s file.txt

• Monitor a Log File in Real Time:

  ./cc -f logfile.log

• Enhanced Formatting with All Transformations:

  ./cc -A file.txt

🔧 Installation & Compilation

Prerequisites

• A C compiler supporting C99 (or later) such as gcc or clang.
• Standard development tools on your platform (e.g., GNU Make, if using a Makefile).

Building from Source

1. Clone the Repository:

   git clone https://github.com/itlwas/cc.git
   cd cc

2. Compile the Code: For maximum optimization and resource efficiency, compile with the following flags:

   gcc -O3 -march=native -fdata-sections -pthread -ffunction-sections -Wl,--gc-sections -s cc.c -o cc

   On Windows, adjust the command accordingly to produce cc.exe.

3. Run the Application:

   ./cc [OPTIONS] [FILE]...
