239 Treats the input as a sequence of newline or end-of-file terminated variable
240 length records independent of input and output block boundaries.
246 Input records shorter than the conversion record size are padded with spaces.
247 Input records longer than the conversion record size are truncated.
248 The number of truncated input records, if any, are reported to the standard
249 error output at the completion of the copy.
264 There are four conversion maps for

309 conversion is also specified, any missing input data will be replaced

321 conversion is not specified, the input block is omitted from the output.
335 If the input file is not a multiple of the output block size
336 after conversion, this conversion forces the final output block

343 If one or more output blocks would consist solely of

404 conversion value was specified and the input line was too long to
405 fit in the conversion record or was not newline terminated.
407 Normally, data resulting from input or conversion or both are aggregated
408 into output blocks of the specified size.
409 After the end of input is reached, any remaining output is written as

454 To create an image of a Mode-1 CD-ROM, which is a commonly used format
455 for data CD-ROM disks, use a block size of 2048 bytes:
457 .Dl "dd if=/dev/cd0 of=filename.iso bs=2048"
459 Write a filesystem image to a memory stick, padding the end with zeros,

499 subsystem might prevent the super-user from writing blocks to a disk.
