<title>Description</title>
<para><command>systemd-activate</command> can be used to
launch a socket activated daemon from the command line for
testing purposes. It can also be used to launch single instances
of the daemon per connection (inetd-style).
</para>
<para>The daemon to launch and its options should be specifed
after options intended for <command>systemd-activate</command>.
</para>
<para>If the <option>-a</option> option is given, file descriptor
of the connection will be used as the standard input and output of
the launched process. Otherwise, standard input and output will be
inherited, and sockets will be passed through file descriptors 3
and higher. Sockets passed through <varname>$LISTEN_FDS</varname>
to <command>systemd-activate</command> will be passed through to
the dameon, in the original positions. Other sockets specified
with <option>--listen</option> will use consecutive descriptors.
