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

       -h, --help
           Display help text and exit.

       -V, --version
           Print version and exit.

FILES

       /etc/rc.local
