If you’re a system administrator, you know the importance of being able to restart your server quickly and efficiently in case of errors or updates.

Introduction:
Before we jump into the steps necessary to restart your Ubuntu server from the terminal, it’s important to understand what exactly the terminal is and why it’s such an essential tool for system administrators.
The terminal in Ubuntu is the command-line interface, which is a way to communicate with your computer through written commands rather than the traditional graphical user interface. Using the terminal allows you to execute commands more quickly and efficiently than going through the traditional software menus.
Now that we know what the terminal is, let’s dive into why you may want to restart your Ubuntu server from the terminal.
Restarting your server can help close any open applications that may be causing your server to experience errors or issues. Additionally, it can initiate system wide updates that are necessary for your server’s security and performance.
Now that we’ve covered the basics of the terminal and why it’s important to restart your server, let’s dive into how to restart your Ubuntu server from the terminal.
