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
   current setting.

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

OPTIONS

   -V, --version

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