Add your public SSH key to a server in one command

cat .ssh/ | ssh hostname 'cat >> .ssh/authorized_keys'
Just run the command, type your password, and that's the last time you need to enter your password for that server. This assumes that the server supports publickey authentication. Also, the permissions on your home dir are 755, and the permissions on your .ssh dir are 700 (local and remote).

"ssh-copy-id" command is more easy to copy public SSH key. ssh-copy-id -i .ssh/
