<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
<para>The command line may carry a list of
environment variables to send as part of the status
<para>The following options are understood:</para>
<listitem><para>Prints a short help
text and exits.</para></listitem>
<listitem><para>Inform the init system
about service start-up
completion. This is equivalent to
READY=1</command>. For details about
the semantics of this option see
<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
MAINPID=$PID</command>. For details
about the semantics of this option see
<listitem><para>Send a free-form
status string for the daemon to the
init systemd. This option takes the
status string as argument. This is
equivalent to <command>systemd-notify
STATUS=...</command>. For details
about the semantics of this option see
<listitem><para>Returns 0 if the
system was booted up with systemd,
non-zero otherwise. If this option is
passed no message is sent. This option
is hence unrelated to the other
options. For details about the
semantics of this option see
<title>Exit status</title>
<para>On success 0 is returned, a non-zero failure
code otherwise.</para>
