# Terminal Essentials

* `apt` (Advanced Package Tool): The core package manager for Ubuntu. Used to install (`apt install`), remove (`apt remove`), and search for software.
* `wget`: A non-interactive network downloader. Used to download files directly from URLs.
  * *Example:* `wget https://example.com/file.zip`
* `curl`: A tool to transfer data to or from a server. Developers use it heavily to test REST APIs.
  * *Example:* `curl -X GET https://api.github.com/users`
* `echo`: Prints text to the terminal, or more commonly, pipes text into a file.
  * *Example:* `echo "Hello World" > test.txt`
* `nano`: A simple, beginner-friendly terminal text editor. Perfect for quickly editing configuration files.
  * *Example:* `nano ~/.bashrc`
* `sudo` (SuperUser DO): Temporarily elevates your privileges to "root" (the absolute administrator) to execute system-level commands.
