	10 .Sh DESCRIPTION
	11 .Nm
	12 copies the standard input to the standard output. By default input data …
	13 read and written in 64kB blocks. When finished,
	14 .Nm
	15 displays the number of records read and written as well as the total num…
	16 of bytes copied.
	17 .Nm
	18 syncs the filesystem once it is done copying. If you want to disable tha…
	19 the
	20 .Ar nosync
	21 option.

	23 .Bl -tag -width Ds
	24 .It Ar bs Ns Op Ar =N
	25 If
	26 .Ar bs
	27 is not specified, the default blocksize is 64kB. If
	28 .Ar bs
	29 is specified
	30 without setting it to a specific value then an optimal value between the
	31 source and target filesystem will be selected. If this process fails it …
	32 fallback to the system's pagesize. Adjust
	33 .Ar N
	34 to set the block size of the transfers in bytes.
	35 .It Ar count=N
	36 Copy only
	37 .Ar N
	38 input blocks.
	39 .It Ar direct
	40 Use direct I/O for data.
	41 .It Ar if=file
	42 Read input from
	43 .Ar file
	44 instead of the standard input.
	45 .It Ar nosync
	46 Do not sync the filesystem once we are done copying.
	47 .It Ar quiet
	48 Enable quiet output.
	49 .It Ar of=file
	50 Write output to
	51 .Ar file
	52 instead of the standard output. If an initial portion of the output
	53 .Ar file
	54 is skipped using the seek operand, the output file is truncated at that
	55 point.
	56 .It Ar seek=N
	57 Seek
	58 .Ar N
	59 blocks from the beginning of the output before copying.
	60 .It Ar skip=N
	61 Skip
	62 .Ar N
	63 blocks from the beginning of the input before copying.
	64 .It Ar conv=notrunc
	65 Do not truncate the output file.
