Ssh -i

-i identity_file
Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is 
~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for protocol version 2. Identity 
files may also be specified on a per-host basis in the configuration file. It is possible to have multiple -i 
options (and multiple identities specified in configuration files)
