ssh-import-id-lp USER_ID_1 [USER_ID_2] … [USER_ID_n]

ssh-import-id-gh USER_ID_1 [USER_ID_2] … [USER_ID_n]

OPTIONS

-h | –help usage
-o | –output F write output to file ‘F’ (default ~/.ssh/autho‐
rized_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

DESCRIPTION

This 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 https://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.
