<H2>DESCRIPTION</H2>
|
|
|
|
Based on examination of the
|
|
<I>linux/kernel/reboot.c</I>
|
|
|
|
code, it is clear that there are two supported functions that the
|
|
Ctrl-Alt-Del sequence can perform.
|
|
<DL COMPACT>
|
|
<DT id="1"><B>hard</B>
|
|
|
|
<DD>
|
|
Immediately reboot the computer without calling
|
|
<B><A HREF="/cgi-bin/man/man2html?2+sync">sync</A></B>(2)
|
|
|
|
and without any other preparation. This is the default.
|
|
<DT id="2"><B>soft</B>
|
|
|
|
<DD>
|
|
Make the kernel send the SIGINT (interrupt) signal to the
|
|
<B>init</B>
|
|
|
|
process (this is always the process with PID 1). If this option is used,
|
|
the
|
|
<B><A HREF="/cgi-bin/man/man2html?8+init">init</A></B>(8)
|
|
|
|
program must support this feature. Since there are now several
|
|
<B><A HREF="/cgi-bin/man/man2html?8+init">init</A></B>(8)
|
|
|
|
programs in the Linux community, please consult the documentation for the
|
|
version that you are currently using.
|
|
</DL>
|
|
<P>
|
|
|
|
When the command is run without any argument, it will display the current
|
|
setting.
|
|
<P>
|
|
|
|
The function of
|
|
<B>ctrlaltdel</B>
|
|
|
|
is usually set in the
|
|
<I>/etc/rc.local</I>
|
|
|
|
file.
