CTRLALTDEL(8)						     Linux Programmer's Manual						     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 documenta-
       tion for the version that you are currently using.

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