Remember, we mentioned that there are basically two methods for
duplicating media. The first was with tar. The second is with the
duplicating media. The first was with cpio. The second is with the
dd utility. On systems with TWO tape/cartridge/disk drives you
may copy from one to the other using dd. You may also copy directly
from the tape drive to a data cartridge drive, or from a disk drive
to a data cartridge drive, etc. We'll use duplicating disks for our
examples, however, you may use this procedure for other devices as well.
dd
SYNTAX
dd [option=value] ...
FUNCTION
dd copies the specified input file to the specified output
file with possible conversions. The standard input and output
are used by default.
OPTIONS
option values
if=name input file is name; standard input is default
of=name output file is name; standard output is default
ibs=n input block size of n bytes (default 512)
obs=n output block size (default 512)
files=n copy n input files before terminating.
The dd command has many qualifiers and specifiers.
Let us briefly cover a few.
* The if (input file) option allows you to read
from the named file, instead of standard input.
* The of (output file) option allows you to write
to the named file, instead of standard output.
* The ibs (input block size) option specifies
the block size of the input media.
* The obs (output block size) option specifies
the block size of the output media.
To copy the contents of floppy drive 1 to floppy drive 2, you would enter
dd if=/dev/rsave1 of=/dev/rsave2
* The if= option tells dd that the input will come
from /dev/rsave1 rather than the standard input.
* The file /dev/rsave1 is floppy drive 1.
* The of= option tells dd that the output will
go to /dev/rsave2 rather than the standard output.
* The file /dev/rsave2 is floppy drive 2.
Let us use the dd command to
copy from one floppy to the other
on your system. So please type:
dd if=/dev/rsave1 of=/dev/rsave2
