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 sup-
       ported functions that the Ctrl-Alt-Del sequence can perform: a hard reset,  which  immedi-
       ately 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.
