ssh-copy-id - install your public key in a remote machine's authorized_keys
2. SYNOPSIS ▲
ssh-copy-id [-i [identity_file]] "[user@]machine"
3. DESCRIPTION ▲
R ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities)
It also changes the permissions of the remote user's home,
R ~/.ssh , and
~/.ssh/authorized_keys to remove group writability (which would otherwise prevent you from logging in, if the remote
StrictModes set in its configuration).
-i option is given then the identity file (defaults to
R ~/.ssh/id_rsa.pub ) is used, regardless of whether there are any keys in your
R ssh-agent . Otherwise, if this:
provides any output, it uses that in preference to the identity file.
-i option is used, or the
ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fingerprints (by whatever means) it uses ssh to append them to
~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary)
