Adding Default Keys

In the simplest form, ssh-add can be run without arguments. Used this way, it adds the default keys ~/.ssh/id_rsa, ~/.ssh/id_dsa, ~/.ssh/id_ecdsa. ~/ssh/id_ed25519, and ~/.ssh/identity, if they exist.

Source

Adding an Arbitrary Key

To add an arbitrary private key, give the path of the key file as an argument to ssh-add. For example,

ssh-add ~/.ssh/tatu-aws-key

would add the file ~/.ssh/tatu-aws-key.
