CTRLALTDEL(8)              Linux Programmer’s Manual             CTRLALTDEL(8)




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 supported functions that the  Ctrl-Alt-Del  sequence  can
       perform:  a  hard reset, which immediately 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.
