ssh-copy-id for OS X

Content

To use ssh-copy-id in OS X, do the following on the command line.

$ cd $ curl https://gist.github.com/darklaunch/5045167/raw --output ssh-copy-id $ chmod +x ssh-copy-id $ ./ssh-copy-id -i ~/.ssh/id_rsa.pub username@hostname

Also, if haven't created key for a specific email address, do this first:

$ ssh-keygen -t rsa -C "username@example.com"

And wherever you save the key, specify that in the ssh-copy-id command by replacing "~/.ssh/id_rsa.pub" with the appropriate path

Here's a copy of the script for reference
