+ used to escape and to undo escaping of strings.</para>
+
+ <para>The command takes any number of strings on the command line,
+ and will process them individually, one after another. It will
+ output them separated by spaces to stdout.</para>
+
+ <para>By default, this command will escape the strings passed,
+ unless <option>--unescape</option> is passed which results in the
+ inverse operation being applied. If <option>--mangle</option> is given, a
+ special mode of escaping is applied instead, which assumes the
+ string is already escaped but will escape everything that
+ appears obviously non-escaped.</para>

+ <title>Description</title>
+
+ <para><command>systemd-notify</command> may be called by daemon
+ scripts to notify the init system about status changes. It can be
+ used to send arbitrary information, encoded in an
+ environment-block-like list of strings. Most importantly, it can be
+ used for start-up completion notification.</para>
+
+ <para>This is mostly just a wrapper around
+ <function>sd_notify()</function> and makes this functionality
+ available to shell scripts. For details see
+ <citerefentry><refentrytitle>sd_notify</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+ </para>
+
+ <para>The command line may carry a list of environment variables
+ to send as part of the status update.</para>
+
+ <para>Note that systemd will refuse reception of status updates
+ from this command unless <varname>NotifyAccess=all</varname> is
+ set for the service unit this command is called from.</para>
+
+ </refsect1>
+
+ <refsect1>
+ <title>Options</title>
+
+ <para>The following options are understood:</para>
+
+ <variablelist>
+ <varlistentry>
+ <term><option>--ready</option></term>
+
+ <listitem><para>Inform the init system about service start-up
+ completion. This is equivalent to <command>systemd-notify
+ READY=1</command>. For details about the semantics of this
+ option see

+ </varlistentry>
+
+ <varlistentry>
+ <term><option>--pid=</option></term>
+
+ <listitem><para>Inform the init system about the main PID of
+ the daemon. Takes a PID as argument. If the argument is
+ omitted, the PID of the process that invoked
+ <command>systemd-notify</command> is used. This is equivalent
+ to <command>systemd-notify MAINPID=$PID</command>. For details
+ about the semantics of this option see
+ <citerefentry><refentrytitle>sd_notify</refentrytitle><manvolnum>3</manvolnum></citerefentry>.</para></listitem>

+ argument. This is equivalent to <command>systemd-notify
+ STATUS=...</command>. For details about the semantics of this

+
+ <listitem><para>Returns 0 if the system was booted up with

+ alternate way to check for this state is to call
+ <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ with the <command>is-system-running</command> command. It will

+
+ <para>The daemon to launch and its options should be specified
+ after options intended for <command>systemd-socket-activate</command>.
+ </para>
+
+ <para>If the <option>--inetd</option> option is given, the socket file descriptor 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-socket-activate</command> will be passed through to the daemon, in the original positions. Other sockets
+ specified with <option>--listen=</option> will use consecutive descriptors. By default,
+ <command>systemd-socket-activate</command> listens on a stream socket, use <option>--datagram</option> and
+ <option>--seqpacket</option> to listen on datagram or sequential packet sockets instead (see below).
