.SH "DESCRIPTION"

.PP
\fBAmdd\fR provides just enough of the standard UNIX \fBdd\fR command for the needs of \fBAmanda\fR\&. This is handy when doing a full restore and the standard \fBdd\fR program has not yet been found\&.

.PP
\fBAmdd\fR also provides access to the \fBAmanda\fR output drivers that support various tape simulations\&. This may be used for debugging or to convert from one format to another\&.

.PP
See the \fBamanda\fR(8) man page for more details about \fBAmanda\fR\&. See the \fBOUTPUT DRIVERS\fR section of \fBamanda(8)\fR for more information on the \fBAmanda\fR output drivers\&.

.SH "OPTIONS"

.TP
\fB\-d\fR
Turn on debugging output\&.

.TP
\fB\-l\fR\fIlength\fR
Set the output length\&. If the output driver limits the output size, this controls when end of tape will be simulated\&.

\fBLength\fR may have a multiplier suffix:


.nf

k \-> 1024 (Kilobytes)
b \-> 512 (Blocks)
M \-> 1024*1024 (Megabytes)

.fi
The default is no multiplier (bytes)\&.

.TP
\fBif=\fR\fBinput\fR
Input to \fBdd\fR\&. Default is stdin\&.

.TP
\fBof=\fR\fBoutput\fR
Where to send the output of \fBdd\fR\&. Default is stdout\&.

.TP
\fBbs=\fR\fBblocksize\fR
Size of each record\&. Input records smaller than this will \fBnot\fR be padded\&. Output records will be the same size as the corresponding input record\&. Default is 512 bytes\&.

\fBBlocksize\fR may have a multiplier suffix:


.nf

k \-> 1024 (Kilobytes)
b \-> 512 (Blocks)
M \-> 1024*1024 (Megabytes)

.fi
The default is no multiplier (bytes)\&.

.TP
\fBcount=\fR\fBcount\fR
Number of records to copy\&. Default is all records until end of file\&.

.TP
\fBskip=\fR\fBcount\fR
Number of records to skip before copying input to output\&. Default is zero\&.
