flatpak-override — Override application requirements

Synopsis

flatpak override [OPTION...] APP

Description

Overrides the application specified runtime requirements. This can be used to grant a sandboxed application more or less resources than it requested.

By default the application gets access to the resources it requested when it is started. But the user can override it on a particular instance by specifying extra arguments to flatpak run, or every time by using flatpak override.
