+.TH CTRLALTDEL 8 "October 2015" "util-linux" "System Administration"
+.SH NAME
+ctrlaltdel \- set the function of the Ctrl-Alt-Del combination
+.SH SYNOPSIS
+.BR "ctrlaltdel hard" | soft
+.SH DESCRIPTION
+Based on examination of the
+.I linux/kernel/reboot.c
+code, it is clear that there are two supported functions that the
+Ctrl-Alt-Del sequence can perform.
+.TP
+.B hard
+Immediately reboot the computer without calling
+.BR sync (2)
+and without any other preparation. This is the default.
+.TP
+.B soft
+Make the kernel send the SIGINT (interrupt) signal to the
+.B init
+process (this is always the process with PID 1). If this option is used,
+the
+.BR init (8)
+program must support this feature. Since there are now several
+.BR init (8)
+programs in the Linux community, please consult the documentation for the
+version that you are currently using.
+.PP
+When the command is run without any argument, it will display the current
+setting.
+.PP
+The function of
+.B ctrlaltdel
+is usually set in the
+.I /etc/rc.local
+file.
