<h3>Name</h3>
halt - halt system
<h3>Synopsis</h3>
/sbin/halt
<h3>Description</h3>
halt shuts the system down. A clean shutdown is performed, flushing
buffers to disk, unmounting filesystems, and so forth.
<p>
Once shutdown is complete, halt stops execution of the operating
system. What this entails depends on the platform. On platforms with a
hardware boot monitor, it normally returns to the boot monitor. On
software-based platforms, such as System/161, it normally terminates
the software simulation. On other platforms the system will generally
wait for a keystroke on the console and then reboot.
<p>
<h3>Requirements</h3>
halt uses the <A HREF=../syscall/reboot.html>reboot</A> system call.
<p>
halt will function properly even before you do any work on OS/161.
