Module dd_lib::opts

configuration and parsing

bs=n

Set both input and output block size to n bytes, superseding the ibs and obs operands. If no conversion values other than noerror, notrunc or sync are specified, then each input block is copied to the output as a single block without any aggregation of short blocks.

cbs=n

Set the conversion record size to n bytes. The conversion record size is required by the record oriented conversion values.

conv=value[,value …]

See flags/cflag

files=n

Copy n input files before terminating. This operand is only applicable when the input device is a tape.

ibs=n

Set the input block size to n bytes instead of the default 512.

if=file

Read input from file instead of the standard input.

iflag=FLAGS

See flags/iflag

iseek=n

Seek on the input file n blocks. This is synonymous with skip=n.

obs=n

Set the output block size to n bytes instead of the default 512.

of=file

Write output to file instead of the standard output. Any regular output file is truncated unless the notrunc conversion value is specified. If an initial portion of the output file is seeked past (see the oseek operand), the output file is truncated at that point. #### oseek=n
Seek on the output file n blocks. This is synonymous with seek=n.

oflag=FLAGS

write as per the comma separated symbol list

seek=n

Seek n blocks from the beginning of the output before copying. On non-tape devices, an lseek(2) operation is used. Otherwise, existing blocks are read and the data discarded. If the user does not have read permission for the tape, it is positioned using the tape ioctl(2) function calls. If the seek operation is past the end of file, space from the current end of file to the specified offset is filled with blocks of NUL bytes.

skip=n

Skip n blocks from the beginning of the input before copying. On input which supports seeks, an lseek(2) operation is used. Otherwise, input data is read and discarded. For pipes, the correct number of bytes is read. For all other devices, the correct number of blocks is read without distinguishing between a partial or complete block being read. error types and handling for command line options
