Summary
In this chapter, we learned how sandbox applications work, from a very illustrative example using SELinux and Firefox, to portable application formats widely used today.
We explored AppImage apps, from how to run them to using the AppImageKit to generate AppImages.
Finally, we took a deep look at Flatpak applications, a format that supports the Fedora Project and even maintains its own version of Fedora Flatpaks based on RPMs.
We also learned how to use the command line to extend the administration and use of sandboxed applications.
In the next chapter, we will take a walk through the most popular terminal-based text editors, plus look at some usage tricks and customizations.
