CTRLALTDEL(8)                System Administration               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/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 cur-
       rent setting.

       The function of ctrlaltdel is usually set in the /etc/rc.local file.
