       flatpak-enter - Enter an application


       flatpak enter [OPTION...] INSTANCE COMMAND [ARG...]


       Enter a running sandbox.  INSTANCE must be either the pid of a process running in a
       flatpak sandbox, or the ID of a running application or a the instance ID of a running
       sandbox.  COMMAND is the command to run in the sandbox. Extra arguments are passed on to
       the command.

       This creates a new process within the running sandbox, with the same environment. This is
       useful when you want to debug a problem with a running application.

       This command requires extra privileges, so must be run as root or via e.g. sudo. To get
       TAB completion for the application ID, use sudo -E.


       The following options are understood:

       -h, --help
           Show help options and exit.

       -v, --verbose
           Print debug information during command processing.

           Print OSTree debug information during command processing.
