I am trying to do the following
su - operator -c "ssh-keygen -t dsa -f ~/.ssh/id_dsa << EOF
EOF"
from a ksh script
But each time I run it I have to press carriage return twice ...
When I run the above with out the "su -operator -c"
It works fine.

The version of ssh-keygen I have does a number of things to get the
password.
It looks to see if the standard input is connected to a terminal.
If not then it either calls ssh-askpass or it opens /dev/tty, and reads
from that. This explains why you have to press enter twice.
At least my version of ssh-keygen has a -N flag so you can say
su - operator -c "ssh-keyget -N '' -t dsa -f ~/.ssh/id_dsa"
