How to get rid of extra enter at the end???

Hi guys,

I want to automate a few tasks. For one of them, I need to get the output of a command and parse it to extract information I need: drbdadm create-md drbd0

The output is:

md_offset 48010952704
al_offset 48010919936
bm_offset 48009453568

Found ext2 filesystem which uses 18563076 kB
current configuration leaves usable 46884232 kB

==> This might destroy existing data! <==

Do you want to proceed?
[need to type 'yes' to confirm]

Now, I need to enter no at this stage so that I could get the size only. What I do is:

But, this requires me to press enter at the command prompt before it finishes the execution.

How do I get rid of that extra enter? Anybody? please help!

Thanks

Try:

test=`drbdadm create-md drbd0 << MAYDAY | grep "current configuration leaves usable" 
no

MAYDAY
