CTRLALTDEL(8) Linux Programmer's Manual CTRLALTDEL(8)
NAME
ctrlaltdel - set the function of the Ctrl-Alt-Del combina-
tion
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 ver-
sion that you are currently using.
ctrlaltdel is usually used in the /etc/rc.local file.
