In the following tutorial, you will learn how to install ExifTool on Ubuntu 22.10. The tutorial will use the command line terminal with complete steps using both the standard APT repository from Jammy and the Flatpak hub repository as an alternative for those that may want a newer version.
ExifTool implements its own open metadata format. It is designed to encapsulate metainformation from many sources, in binary or textual form, and bundle it together with any type of file. It can either be a single file, wrapping existing data, or used as a sidecar file, carrying for example Exif or XMP metadata.
