- DD(1) Minix Programmer's Manual DD(1)
- NAME
- dd - disk dumper
- SYNOPSIS
- dd [option = value] ...
- EXAMPLES
- dd if=/dev/fd0 of=/dev/fd1
- # Copy disk 0 to disk 1
- dd if=x of=y bs=1w skip=4
- # Copy x to y, skipping 4 words
- dd if=x of=y count=3
- # Copy three 512-byte blocks
- DESCRIPTION
- This command is intended for copying partial files. The block size, skip
- count, and number of blocks to copy can be specified. The options are:
- if = file - Input file (default is stdin)
- of = file - Output file (default is standard output)
- ibs = n - Input block size (default 512 bytes)
- obs = n - Output block size (default is 512 bytes)
- bs = n - Block size; sets ibs and obs (default is 512 bytes)
- skip = n - Skip n input blocks before reading
- seek = n - Skip n output blocks before writing
- count = n - Copy only n input blocks
- conv = lcase - Convert upper case letters to lower case
- conv = ucase - Convert lower case letters to upper case
- conv = swab - Swap every pair of bytes
- conv = noerror - Ignore errors and just keep going
- conv = silent - Suppress statistics (Minix specific flag)
- Where sizes are expected, they are in bytes. However, the letters w, b,
- or k may be appended to the number to indicate words (2 bytes), blocks
- (512 bytes), or K (1024 bytes), respectively. When dd is finished, it
- reports the number of full and partial blocks read and written.
