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/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  sup‐
       port  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.

OPTIONS
       -V, --version
              Output version information and exit.

       -h, --help
              Display help and exit.
