NAME

6       ctrlaltdel - set the function of the Ctrl-Alt-Del combination
7

SYNOPSIS

9       ctrlaltdel hard|soft
10

DESCRIPTION

12       Based on examination of the linux/kernel/reboot.c code, it is clear
13       that there are two supported functions that the <Ctrl-Alt-Del> sequence
14       can perform.
15
16       hard
17           Immediately reboot the computer without calling sync(2) and without
18           any other preparation. This is the default.
19
20       soft
21           Make the kernel send the SIGINT (interrupt) signal to the init
22           process (this is always the process with PID 1). If this option is
23           used, the init(8) program must support this feature. Since there
24           are now several init(8) programs in the Linux community, please
25           consult the documentation for the version that you are currently
26           using.
27
28       When the command is run without any argument, it will display the
29       current setting.
30
31       The function of ctrlaltdel is usually set in the /etc/rc.local file.
32

OPTIONS

38           Print version and exit.
