Journald is a logging system used in modern Linux-based operating systems to record system events. It collects information about the operation of various services, applications, and system processes to help administrators monitor system health and diagnose errors.

Unlike standard text logs, journald stores data in a binary format. This allows logs to be stored more compactly and managed more efficiently, but at the same time, you cannot simply open these logs in a text editor. Special tools are required to view and analyze them.

In this article, we will look at how to view the records maintained by journald and how to clear them to save disk space.

Running out of space on your server? This may cause the site and database to malfunction. To free up space, you need to identify the files taking up the most room and delete them. In this article, we’ll explain how to easily accomplish this using the ncdu utility and how to safely clean up logs.

If you also work with ZIP or TAR archives, check out our guides on handling them in the Linux command line.

ZIP is one of the most popular archiving formats. Unlike a home PC that allows you to work with such archives in a convenient graphical interface, most servers don’t provide such an opportunity. So, be sure to know the basic commands to perform typical tasks via a command prompt.
