the standard input is used.

The offset argument specifies the offset
in the file where dumping is to commence.
This argument is normally interpreted
as octal bytes.
If `\fB.\fR' is appended, the offset is interpreted in
decimal.
If `\fBb\fR' is appended, the offset is interpreted in
blocks of 512 bytes.
If the file argument is omitted,
the offset argument must be preceded 
.RB ` + '.

Dumping continues until end-of-file.
