- \fBb\fR interprets bytes in octal.

- The \fIfile\fR argument specifies which file is to be dumped.
- If no file argument is specified,
- the standard input is used.
- Thus
- .it od
- can be used as a filter.
- .s3
- 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.
- (A block is 512 bytes.)
- If the file argument is omitted,
- the offset argument must be preceded by `\fB+\fR'.
- .s3
- Dumping continues until end-of-file.
