How many times have you ran through this series of events?
$ cat ~/.ssh/id_dsa.pub
...copy output to clipboard...
$ ssh myhost
...enter password...
myhost$ vi ~./ssh/authorized_keys
...paste public key and save...
myhost$ exitThanks to bash’s tab completion, I happened upon ssh-copy-id. Instead of all that above, just do this:
$ ssh-copy-id myhost
...enter password...You’re done!
