Ug. no. That is way way insecure.

Most modern distros have an ssh-agent running as a parent of all
X-spawned processed (including processes spawned by xterms). So, one
only needs to run
ssh-add ~/.ssh/id_dsa ~/.ssh/identity
once, and input your password once. After that, no passwords are

For those with multiple peer shells and no X-parented ssh-agent, you
will need to run ssh-agent ONCE, like so:

ssh-agent > ~/tmp/ssh-agent.out

and then for each shell, you need to run:

eval `cat ~/tmp/ssh-agent.out`

and then run the ssh-add command from above.
