ctrlaltdel: set the function of the Ctrl-Alt-Del combination
NAMEctrlaltdel - set the function of the Ctrl-Alt-Del combination
DESCRIPTIONBased 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.
- -V, --version
- Display version information and exit.
- -h, --help
- Display help text and exit.
