Basic Linux Command Using Ubuntu terminal environment.

Ubuntu Terminal Environment
The Ubuntu terminal environment is a powerful tool that allows users to interact with the Ubuntu operating system directly via text-based commands. It is often referred to as the command line interface (CLI) and is built on the Bash shell by default. The terminal is essential for executing programs, managing files, installing packages, monitoring processes, and performing administrative tasks. It is a lightweight and faster alternative to the graphical user interface (GUI) for many tasks, offering more control and automation. However, it also has a steeper learning curve for beginners and can be more error-prone if commands are not executed correctly.
