NAME

       flatpak-spawn - Run commands in a sandbox

SYNOPSIS

       flatpak-spawn [OPTION...] COMMAND [ARGUMENT...]

DESCRIPTION

       Unlike other flatpak commands, flatpak-spawn is available to applications inside the
       sandbox. It runs COMMAND outside the sandbox: either in another sandbox, or on the host.

       When called without --host, flatpak-spawn uses the Flatpak portal to create a copy of the
       sandbox it was called from, optionally using tighter permissions and optionally the latest
       version of the app and runtime (see --latest-version).

OPTIONS

       The following options are understood:

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

       -v, --verbose
           Print debug information

       --forward-fd=FD
           Forward a file descriptor

       --clear-env
           Run with a clean environment

       --watch-bus
           Make the spawned command exit if the caller disappears from the session bus

       --env=VAR=VALUE
           Set an environment variable

       --latest-version
           Use the latest version of the refs that are used to set up the sandbox

       --no-network
           Run without network access

       --sandbox
           Run fully sandboxed. See the documentation for the --sandbox option in flatpak-run(1)

           See the --sandbox-expose and --sandbox-expose-ro options for selective file access.

       --sandbox-expose=NAME
           Expose read-write access to a file in the sandbox.

           Note that absolute paths or subdirectories are not allowed. The files must be in the
           sandbox subdirectory of the instance directory (i.e.  ~/.var/app/$APP_ID/sandbox).

           This option is useful in combination with --sandbox (otherwise the instance directory
           is accessible anyway).

       --sandbox-expose-ro=NAME
           Expose readonly access to a file in the sandbox.

           Note that absolute paths or subdirectories are not allowed. The files must be in the
           sandbox subdirectory of the instance directory (i.e.  ~/.var/app/$APP_ID/sandbox).

           This option is useful in combination with --sandbox (otherwise the instance directory
           is accessible anyway).

       --host
           Run the command unsandboxed on the host. This requires access to the
           org.freedesktop.Flatpak D-Bus interface.

       --directory=DIR
           The working directory in which to run the command.

           Note that the given directory must exist in the sandbox or, when used in conjunction
           with --host, on the host.

EXAMPLES

       $ flatpak-spawn ls /var/run
