CTRLALTDEL(8)                System Administration               CTRLALTDEL(8)

NAME
       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS
       ctrlaltdel hard|soft

DESCRIPTION
       Based  on  examination of the linux/kernel/sys.c code, it is clear that
       there are two supported functions that the  Ctrl-Alt-Del  sequence  can
       perform:  a  hard reset, which immediately reboots the computer without
       calling sync(2) and without any other preparation; and  a  soft  reset,
       which  sends the SIGINT (interrupt) signal to the init process (this is
       always the process with PID 1).  If this option is  used,  the  init(8)
       program must support this feature.  Since there are now several init(8)
       programs in the Linux community, please consult the  documentation  for
       the version that you are currently using.

       ctrlaltdel is usually used in the /etc/rc.local file.
