-h | --help usage
-o | --output F write output to file 'F' (default ~/.ssh/authorized_keys, use "-" for standard out)
-r | --remove remove keys from authorized keys file 'F'
-u | --useragent U append U to the user agent string
PROTO:USER_ID Protocol can be 'lp' for Launchpad.net, or 'gh' for Github.com
DESCRIPTIONThis utility will securely contact a public keyserver and retrieve one or more user's public keys, and append these to the current user's ~/.ssh/authorized_keys file, standard output or any other specified output file.
User IDs can be prepended by a protocol:
- lp: to use launchpad.net/~%s/+sshkeys
- gh: to use https://api.github.com/users/%s/keys
If the protocol is not explicitly specified, then ssh-import-id will read a URL variable string from /etc/ssh/ssh_import_id as installed by your package manager and configured by your system administrator. You can override this locally by exporting the string you want in a URL environment variable. If all of these are empty, then the protocol is assumed to be "lp:", which was the original target implementation of this tool.
Any keys added will be "labled" with a trailing comment, "# ssh-import-id PROTO:USER_ID". Revoking keys will first look for lines in the authorized keys file ending with that label.
