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.
