# `nrt` - A Rust-Based Clone of the `cat` Command

`nrt` is a lightweight and efficient command-line utility built in Rust, designed to replicate and extend the functionality of the classic Unix `cat` command.
Whether you need to quickly view file contents, inspect file metadata, or perform basic file operations, `nrt` provides a versatile toolset.

## Features

`nrt` enhances the standard `cat` command with the following capabilities:

- **File Size**: Display the size of the file in bytes.
- **Creation Time**: Show the creation time of the file in UTC.
- **Last Modified Time**: Display the last modified time of the file in UTC.
- **File Permissions**: List the file's mode (permissions) in numeric form.
- **Line Count**: Count the total number of lines in the file.
- **Non-Empty Lines**: Print all non-empty lines, each with its corresponding line number.
- **Rename Files**: Rename the file to a new specified filename.
- **Copy File Content**: Copy the entire content of the file.
- **Basic Concatenation**: View the content of one or multiple files, similar to the standard `cat` command.

## Installation

To install `nrt`, use `cargo`, Rust's package manager:

```sh
cargo install nrt

```

## Usage

`nrt` is easy to use with a variety of options to suit your needs. The general syntax is:

```sh
nrt <filename> [OPTION]

# Options
    --size: Show the size of the file in bytes.
