Look at ssh-agent and ssh-add.

eval `ssh-agent`
ssh-add

Note back-quotes.  This will start up persistent ssh-agent process.
ssh-add will prompt for passphrase and add key.  You need to kill
ssh-agent manually, it will outlast session, IIRC.  There is a way to
have ssh-agent start a new sub-shell and terminate when sub-shell
exits.  You can add other keys besides default (RSA key in ~/.ssh) by
file name.
