While Ubuntu’s graphical desktop is incredibly user-friendly, learning how to use the command line can unlock a new level of power and efficiency. The command line, or terminal, is a text-based interface that allows you to interact directly with the operating system. For many tasks, it can be much faster and more powerful than a graphical application. This guide will introduce you to some of the most fundamental commands to get you started on your journey.

📂 How to Navigate Your Filesystem
The first set of commands to learn are for navigating your files and directories. The command `pwd` (print working directory) will show you your current location. To see the contents of your current directory, you use `ls` (list). You can change directories using the `cd` (change directory) command, for example, `cd Documents` to move into your Documents folder. To move back up to the parent directory, you use `cd ..`. These three commands are the absolute foundation of command-line navigation.
📝 How to Manage Files and Directories
Once you can navigate, you’ll want to manage your files. You can create a new, empty directory with the `mkdir` (make directory) command, like `mkdir MyNewFolder`. To create a new, empty file, you can use the `touch` command, for example, `touch my_file.txt`. The `cp` command is used to copy files (`cp source.txt destination.txt`), and the `mv` command is used to either move a file to a new location or to rename it (`mv old_name.txt new_name.txt`). Finally, to delete a file, you use the `rm` (remove) command, and to delete an empty directory, you use `rmdir`.
🔑 How to Run Commands with Administrative Privileges
Many system-level tasks, like installing software or modifying system files, require administrative privileges. In Ubuntu, you do this using the `sudo` command, which stands for ‘superuser do.’ By placing `sudo` at the beginning of any command, you are telling the system that you want to run it as the superuser, or root. For example, to update your system’s package list, you would run `sudo apt update`. The system will then prompt you for your user password to verify that you have the authority to perform the action. Using `sudo` is the standard and secure way to perform administrative tasks in Ubuntu.
