ssh-add

Adds private key identities to the authentication agent

Summary

ssh-add adds private key identities to the authentication agent, ssh-agent. When run without arguments, it adds the files ~/.ssh/id_rsa, ~/.ssh/id_dsa, ~/.ssh/id_ecdsa, and ~/.ssh/id_ed25519.

After loading a private key, ssh-add will try to load corresponding certificate information from the filename obtained by appending -cert.pub to the name of the private key file.
