FLATPAK RUN

NAME

flatpak-run − Run an application

SYNOPSIS

flatpak run [OPTION...] APP [ARG...]

DESCRIPTION

Runs an application in a sandboxed environment. APP must name an installed application. Extra arguments are passed on to the application.

flatpak creates a sandboxed environment for the application to run in by mounting the right runtime at /usr and a writable directory at /var, whose content is preserved between application runs. The application itself is mounted at /app.

The details of the sandboxed environment are controlled by the application metadata and various options like −−share and −−socket that are passed to the run command: Access is allowed if it was requested either in the application metadata file or with an option and the user hasn't overridden it.

OPTIONS

The following options are understood:

−h, −−help

Show help options and exit.

−v, −−verbose

Print debug information during command processing.

−−version

Print version information and exit.

−−arch=ARCH

The architecture to install for.

−−command=COMMAND

The command to run instead of the one listed in the application metadata.

−−branch=BRANCH

The branch to use.

−d, −−devel

Use the devel runtime that is specified in the application metadata instead of the regular runtime, and use a seccomp profile that is less likely to break development tools.

−−runtime=RUNTIME

Use this runtime instead of the one that is specified in the application metadata. This is a full tuple, like for example org.freedesktop.Sdk/x86_64/1.2, but partial tuples are allowed. Any empty or missing parts are filled in with the corresponding values specified by the app.

−−runtime−version=VERSION

Use this version of the runtime instead of the one that is specified in the application metadata. This overrides any version specified with the −−runtime option.

−−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.

−−allow=FEATURE

Allow access to a specific feature. This overrides to the Context section from the application metadata. FEATURE must be one of: devel, multiarch. This option can be used multiple times.

−−disallow=FEATURE

Disallow access to a specific feature. This overrides to the Context section from the application metadata. FEATURE must be one of: devel, multiarch. 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.

−−nofilesystem=FILESYSTEM

Remove access to the specified subset of the filesystem from the application. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, xdg−desktop, xdg−documents, xdg−download xdg−music, xdg−pictures, xdg−public−share, xdg−templates, xdg−videos, an absolute path, or a homedir−relative path like ~/dir. 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. 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.

−−talk−name=NAME

Allow the application to talk to the well known name NAME on the session 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.

−−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.

−−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.

−−log−session−bus

Log session bus traffic. This can be useful to see what access you need to allow in your D−Bus policy.

−−log−system−bus

Log system bus traffic. This can be useful to see what access you need to allow in your D−Bus policy.

$ flatpak run org.gnome.GEdit

$ flatpak run −−devel −−command=bash org.gnome.Builder
