- <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.
