dd
DD(1) General Commands 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 writ-
ten.
