NAME
ctrlaltdel - set the function of the Ctrl-Alt-Del combination
SYNOPSIS
ctrlaltdel hard|
soft
DESCRIPTION
Based on examination of the
linux/kernel/reboot.c
code, it is clear that there are two supported functions that the
Ctrl-Alt-Del sequence can perform.
- hard
-
Immediately reboot the computer without calling
sync(2)
and without any other preparation. This is the default.
- soft
-
Make the kernel send 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.
When the command is run without any argument, it will display the current
setting.
The function of
ctrlaltdel
is usually set in the
/etc/rc.local
file.
OPTIONS
- -V, --version
-
Display version information and exit.
- -h, --help
-
Display help text and exit.
FILES
/etc/rc.local
