as <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/<span class="k">\textit</span><span class="nb">{</span>name<span class="nb">}}</span> use <span class="k">\texttt</span><span class="nb">{</span>/etc/rc.common<span class="nb">}</span> as a wrapper.

Example: <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/httpd<span class="nb">}</span>

<span class="k">\begin</span><span class="nb">{</span>Verbatim<span class="nb">}</span>
#!/bin/sh /etc/rc.common
# Copyright (C) 2006 OpenWrt.org

START=50
start() <span class="nb">{</span>
    [ -d /www ] <span class="nb">&amp;&amp;</span> httpd -p 80 -h /www -r OpenWrt
<span class="nb">}</span>

stop() <span class="nb">{</span>
    killall httpd
<span class="nb">}</span>
<span class="k">\end</span><span class="nb">{</span>Verbatim<span class="nb">}</span>

as you can see, the script does not actually parse the command line arguments itself.
This is done by the wrapper script <span class="k">\texttt</span><span class="nb">{</span>/etc/rc.common<span class="nb">}</span>.

<span class="k">\texttt</span><span class="nb">{</span>start()<span class="nb">}</span> and <span class="k">\texttt</span><span class="nb">{</span>stop()<span class="nb">}</span> are the basic functions, which almost any init
script should provide. <span class="k">\texttt</span><span class="nb">{</span>start()<span class="nb">}</span> is called when the user runs <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/httpd start<span class="nb">}</span>
or (if the script is enabled and does not override this behavior) at system boot time.

Enabling and disabling init scripts is done by running <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/<span class="k">\textit</span><span class="nb">{</span>name<span class="nb">}</span> enable<span class="nb">}</span>
or <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/<span class="k">\textit</span><span class="nb">{</span>name<span class="nb">}</span> disable<span class="nb">}</span>. This creates or removes symbolic links to the
init script in <span class="k">\texttt</span><span class="nb">{</span>/etc/rc.d<span class="nb">}</span>, which is processed by <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/rcS<span class="nb">}</span> at boot time.

The order in which these scripts are run is defined in the variable <span class="k">\texttt</span><span class="nb">{</span>START<span class="nb">}</span> in the init
script. Changing it requires running <span class="k">\texttt</span><span class="nb">{</span>/etc/init.d/<span class="k">\textit</span><span class="nb">{</span>name<span class="nb">}</span> enable<span class="nb">}</span> again.

You can also override these standard init script functions:
<span class="k">\begin</span><span class="nb">{</span>itemize<span class="nb">}</span>
    <span class="k">\item</span> <span class="k">\texttt</span><span class="nb">{</span>boot()<span class="nb">}</span> <span class="k">\\</span>
        Commands to be run at boot time. Defaults to <span class="k">\texttt</span><span class="nb">{</span>start()<span class="nb">}</span>

    <span class="k">\item</span> <span class="k">\texttt</span><span class="nb">{</span>restart()<span class="nb">}</span> <span class="k">\\</span>
        Restart your service. Defaults to <span class="k">\texttt</span><span class="nb">{</span>stop(); start()<span class="nb">}</span>

    <span class="k">\item</span> <span class="k">\texttt</span><span class="nb">{</span>reload()<span class="nb">}</span> <span class="k">\\</span>
        Reload the configuration files for your service. Defaults to <span class="k">\texttt</span><span class="nb">{</span>restart()<span class="nb">}</span>

<span class="k">\end</span><span class="nb">{</span>itemize<span class="nb">}</span>

You can also add custom commands by creating the appropriate functions and referencing them
in the <span class="k">\texttt</span><span class="nb">{</span>EXTRA<span class="k">\_</span>COMMANDS<span class="nb">}</span> variable. Helptext is added in <span class="k">\texttt</span><span class="nb">{</span>EXTRA<span class="k">\_</span>HELP<span class="nb">}</span>.

Example:

<span class="k">\begin</span><span class="nb">{</span>Verbatim<span class="nb">}</span>
status() <span class="nb">{</span>
    # print the status info
<span class="nb">}</span>

EXTRA<span class="nb">_</span>COMMANDS=&quot;status&quot;
EXTRA<span class="nb">_</span>HELP=&quot;        status  Print the status of the service&quot;
<span class="k">\end</span><span class="nb">{</span>Verbatim<span class="nb">}</span>
