> dd if=lemonparty.jpg of=\\.\f: bs=512
first of all, there is no need to use if= and of= - that's provided as
a backwards compatability to JCL (HELLO! we're talking punched cards)
Use < and < instead.
i.e.
dd <lemonparty.jpg >\\.\f: bs=512
And yes, when the end of file is reached, dd will halt.
It does not loop the data.
Perhaps you can
1) seek blocks before writing
2) Use a bigger file
For number 1, I think you can do something like (untested)
count=0
while [ $count -lt 500 ]
do
dd <lemonparty.jpg >\\.\f: seeek=$count bs=512
count=`expr $count + 1`
done
For #2, you can use any of these sources of data:
yes | dd bs=512 count=500 >\\.\f:
no | dd bs=512 count=500 >\\.\f:
dd bs=512 count=500 </dev/zero >\\.\f:
dd bs=512 count=500 </dev/urandom >\\.\f:
Usually people use the last one.
And they repeat it if they want to make sure the data has been overwritten.
I suppose you could do
while true
do
cat lemonparty.jpg
done | dd bs=512 count=500 >\\.\f:
Hope that helps
