Only with dd
you can't do this. dd
only copies a byte stream from its input to its output, it can't generate anything. You need to have same source for the dd
which generates the needed data from.
The nearest which you can do that would be a simple shellscript, like this:
for i in $(seq 1 555);do echo -n $i;done
Of course, you can pipe its output into a dd
as well, for example:
for i in $(seq 1 555);do echo -n $i;done|dd bs=4096 count=1
