Overview
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required).
The following options are available:
-
-i file -
Copy the public key contained in file. This option can be specified multiple times and can be combined with the
-loption. If a private key is specified and a public key is found then the public key will be used. -
-l -
Copy the keys currently held by ssh-agent(1). This is the default if the
-ioption was not specified. -
-o ssh-option -
Pass this option directly to ssh(1). This option can be specified multiple times.
-
-p port -
Connect to the specified port on the remote host instead of the default.
-
-v -
Pass -v to ssh(1).
The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name.
Exit status
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs.
Examples
To send a specific key to multiple hosts:
$ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3
