Section (8) ctrlaltdel
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.
Immediately reboot the computer without calling sync(2) and without any other preparation. This is the default.
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
The ctrlaltdel command is part of the util-linux package and is available from Linux Kernel Archive
