NAME ctrlaltdel - set the function of the Ctrl-Alt-Del combination
SYNOPSIS ctrlaltdel hard|soft
DESCRIPTION Based on examination of the linux/kernel/sys.c code, it is clear that there are two sup‐ ported functions that the Ctrl-Alt-Del sequence can perform: a hard reset, which immedi‐ ately reboots the computer without calling sync(2) and without any other preparation; and a soft reset, which sends 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. ctrlaltdel is usually used 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
