NAME         top

       flatpak-enter - Enter an application or runtime's sandbox

SYNOPSIS         top

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

DESCRIPTION         top

       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 the instance ID of
       a running sandbox. You can use flatpak ps to find the instance IDs
       of running flatpaks.

       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 works as a regular user if the system support
       unprivileged user namespace. If that is not available you need to
       run run it like: sudo -E flatpak enter.
