ctrlaltdel
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 -V, --version
Output version information and exit.
-h, --help
Display help and exit.
FILES
/etc/rc.local
SEE ALSO init(8)AUTHOR
Peter Orbaek <poe@daimi.aau.dk>
AVAILABILITY
The ctrlaltdel command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils
/util-linux/>.
