Hmm, this is untested, but you could try something like this:

     echo w flash 0x3fe 0x`echo d cal | avrdude -p tiny12 -t | grep '^0000 ' | 
tr -s ' ' | cut -f2 -d' '` > oscal.tmp
     cat oscal.tmp | avrdude -p tiny12 -t

This is two command lines - on MacOS X at least, I couldn't chain it
into 1 command line because you end up with two instances of avrdude
running and of course the chip doesn't like that.
