.TH CTRLALTDEL 8 "August 2011" "util-linux" "System Administration"
|
|
.SH NAME
|
|
ctrlaltdel \- set the function of the Ctrl-Alt-Del combination
|
|
.SH SYNOPSIS
|
|
.BR "ctrlaltdel hard" | soft
|
|
.SH DESCRIPTION
|
|
Based on examination of the
|
|
.I linux/kernel/sys.c
|
|
code, it is clear that there are two supported functions that the
|
|
Ctrl-Alt-Del sequence can perform: a
|
|
.I hard
|
|
reset, which immediately reboots the computer without calling
|
|
.BR sync (2)
|
|
and without any other preparation; and a
|
|
.I soft
|
|
reset, which sends the SIGINT (interrupt) signal to the
|
|
.B init
|
|
process (this is always the process with PID 1). If this option is used,
|
|
the
|
|
.BR init (8)
|
|
program must support this feature. Since there are now several
|
|
.BR init (8)
|
|
programs in the Linux community, please consult the documentation for the
|
|
version that you are currently using.
|
|
.PP
|
|
.B ctrlaltdel
|
|
is usually used in the
|
|
.I /etc/rc.local
|
|
file.
