\fBctrlaltdel\fR [\fB-hs\fR]
.SH 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)

.TH DD 1 ubase-VERSION
.SH NAME
\fBdd\fR - Copy a file
.SH SYNOPSIS
\fBdd\fR [\fIoperand...\fR]
.SH DESCRIPTION
\fBdd\fR copies the standard input to the standard output. By default input
data is read and written in 64kB blocks. When finished, \fBdd\fR displays the
number of records read and written as well as the total number of bytes copied.
\fBdd\fR syncs the filesystem once it is done copying. If you want
to disable that use the \fInosync\fR option.
.SH OPERANDS
.TP
if=\fIfile\fR
Read input from \fIfile\fR instead of the standard input.
.TP
of=\fIfile\fR
Write output to \fIfile\fR instead of the standard output. If an initial
portion of the output \fIfile\fR is skipped using the seek operand, the output
file is truncated at that point.
.TP
bs[=\fIN\fR]
If bs is not specified, the default blocksize is 64kB. If bs is specified
without setting it to a specific value then an optimal value between the source
and target filesystem will be selected. If this process fails it will fallback
to the system's pagesize. Adjust \fIN\fR to set the block size of the transfers
in bytes.
