NAME

   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.

   Unless overridden with the --user or --installation options, this
   command changes the default system-wide installation.

OPTIONS

   The following options are understood:

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

   --user
       Update a per-user installation.

   --system
       Update the default system-wide installation.

   --installation=NAME
       Updates a system-wide installation specified by NAME among those
       defined in /etc/flatpak/installations.d. Using
       --installation=default is equivalent to using --system.

   --share=SUBSYSTEM
       Share a subsystem with the host session. This overrides the Context
       section from the application metadata. SUBSYSTEM must be one of:
       network, ipc. This option can be used multiple times.

   --unshare=SUBSYSTEM
       Don't share a subsystem with the host session. This overrides the
       Context section from the application metadata. SUBSYSTEM must be
       one of: network, ipc. This option can be used multiple times.

   --socket=SOCKET
       Expose a well-known socket to the application. This overrides to
       the Context section from the application metadata. SOCKET must be
       one of: x11, wayland, pulseaudio, system-bus, session-bus. This
       option can be used multiple times.

   --nosocket=SOCKET
       Don't expose a well-known socket to the application. This overrides
       to the Context section from the application metadata. SOCKET must
       be one of: x11, wayland, pulseaudio, system-bus, session-bus. This
       option can be used multiple times.

   --device=DEVICE
       Expose a device to the application. This overrides to the Context
       section from the application metadata. DEVICE must be one of: dri,
       kvm, all. This option can be used multiple times.

   --nodevice=DEVICE
       Don't expose a device to the application. This overrides to the
       Context section from the application metadata. DEVICE must be one
       of: dri, kvm, all. This option can be used multiple times.

   --filesystem=FS
       Allow the application access to a subset of the filesystem. This
       overrides to the Context section from the application metadata. FS
       can be one of: home, host, xdg-desktop, xdg-documents, xdg-download
       xdg-music, xdg-pictures, xdg-public-share, xdg-templates,
       xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute
       path, or a homedir-relative path like ~/dir or paths relative to
       the xdg dirs, like xdg-download/subdir. The optional :ro suffix
       indicates that the location will be read-only. The optional :create
       suffix indicates that the location will be read-write and created
       if it doesn't exist. This option can be used multiple times.

   --env=VAR=VALUE
       Set an environment variable in the application. This overrides to
       the Context section from the application metadata. This option can
       be used multiple times.

   --own-name=NAME
       Allow the application to own the well-known name NAME on the
       session bus. This overrides to the Context section from the
       application metadata. This option can be used multiple times.

   --talk-name=NAME
       Allow the application to talk to the well-known name NAME on the
       session bus. This overrides to the Context section from the
       application metadata. This option can be used multiple times.

   --system-own-name=NAME
       Allow the application to own the well known name NAME on the system
       bus. If NAME ends with .*, it allows the application to own all
       matching names. This overrides to the Context section from the
       application metadata. This option can be used multiple times.

   --system-talk-name=NAME
       Allow the application to talk to the well known name NAME on the
       system bus. If NAME ends with .*, it allows the application to talk
       to all matching names. This overrides to the Context section from
       the application metadata. This option can be used multiple times.
   `
               .PP --persist=FILENAME
       If the application doesn't have access to the real homedir, make
       the (homedir-relative) path FILENAME a bind mount to the
       corresponding path in the per-application directory, allowing that
       location to be used for persistent data. This overrides to the
       Context section from the application metadata. This option can be
       used multiple times.

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

   --version
