CTRLALTDEL(8) Linux Programmer's Manual CTRLALTDEL(8)
NAME
ctrlaltdel - set(7,n,1 builtins) 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(1,3x,3x clrtobot) that
there are two supported functions that the Ctrl-Alt-Del sequence can
perform: a hard reset(1,7,1 tput), which immediately reboots the computer without
calling sync(1,2,8) (2) and without any other preparation; and a soft reset(1,7,1 tput),
which sends the SIGINT (interrupt) signal(2,7) 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(1,8) the Linux community, please consult the documentation
for the version(1,3,5) that you are currently using.
ctrlaltdel is usually used in(1,8) the /etc/rc.local file.
