# internsctl - Custom Linux Command

## Overview

`internsctl` is a specialized Linux command crafted to offer diverse features for system administrators and interns alike. This command enables users to retrieve details about the CPU, memory, and files on their server. It also facilitates the creation of new users and provides a list of existing users, including those with sudo privileges.

## Installation

1. Clone or download the repository to the local system.

2. Make the `internsctl` script executable using the following command:

   ```bash
   chmod +x internsctl

3. Move the internsctl script to the directory that is in your system's PATH so that you can run it from anywhere.

4. Make sure you have the required permissions to execute the script.
