CTRLALTDEL(8) System Administration 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 documentation for
the version that you are currently using.
ctrlaltdel is usually used in the /etc/rc.local file.
OPTIONS
