How does snap command work internally in Linux?

The snap command in Linux is a package management system that allows users to install and manage software applications packaged as snaps. Snaps are containerized software packages that include all the dependencies required to run the application. This approach ensures that the software runs consistently across different distributions and versions of Linux.

Internally, the snap command interacts with the Snapd daemon, which is responsible for managing the installation, updating, and removal of snap packages. When a user runs the snap command, it communicates with Snapd to perform the requested action. Snapd also provides features such as automatic updates, rollback capabilities, and confinement, which enhances security by isolating applications from each other and the underlying system.

Here's a basic usage example of the snap command:

This command will install the specified snap package. You can also check for updates with:
