CTRLALTDEL(8) System Administration CTRLALTDEL(8)
ctrlaltdel - set the function of the Ctrl-Alt-Del combination
ctrlaltdel hard|soft
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.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
/etc/rc.local
init(8), systemd(1)
