You could redirect stdout to /dev/null:

Code:

dd ... > /dev/null

You'll still get the messages on stderr, but not those on stdout.

Timmeke, on what version of dd did you try this out?
The ones I test (dd (coreutils) 5.93 and dd (coreutils) 5.2.1) write the summary to stderr. In that case you need to redirect stderr -- either of

Code:

dd ... >& /dev/null              for (t)csh, or

dd ... 2> /dev/null              for (ba)sh.

depending on your shell.

I didn't actually test it. I assumed it would print on stdout, as normal tools do.
