`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:

cargo install nrt
