NAME         top

       systemd-stdio-bridge - D-Bus proxy

SYNOPSIS         top

       systemd-stdio-bridge [OPTIONS...]

DESCRIPTION         top

       systemd-stdio-bridge implements a proxy between STDIN/STDOUT and
       a D-Bus bus. It expects to receive an open connection via
       STDIN/STDOUT when started, and will create a new connection to
       the specified bus. It will then forward messages between the two
       connections. This program is suitable for socket activation: the
       first connection may be a pipe or a socket and must be passed as
       either standard input, or as an open file descriptor according to
       the protocol described in sd_listen_fds(3). The second connection
       will be made by default to the local system bus, but this can be
       influenced by the --user, --system, --machine=, and --bus-path=
       options described below.

       sd-bus(3) uses systemd-stdio-bridge to forward D-Bus connections
       over ssh(1), or to connect to the bus of a different user, see

OPTIONS         top

       The following options are understood:

           Talk to the service manager of the calling user, rather than
           the service manager of the system.

           Talk to the service manager of the system. This is the
           implied default.

       -M, --machine=
           Execute operation on a local container. Specify a container
           name to connect to, optionally prefixed by a user name to
           connect as and a separating "@" character. If the special
           string ".host" is used in place of the container name, a
           connection to the local system is made (which is useful to
           connect to a specific user's user bus: "--user
 "). If the "@" syntax is not used, the
           connection is made as root user. If the "@" syntax is used
           either the left hand side or the right hand side may be
           omitted (but not both) in which case the local user name and
           ".host" are implied.

       -p PATH, --bus-path=PATH
           Path to the bus address. Default:

           Added in version 251.

       -h, --help
           Print a short help text and exit.

           Print a short version string and exit.

EXIT STATUS         top

       On success, 0 is returned, a non-zero failure code otherwise.
