What Others Think

Why not use built in `ssh-copy-id` command?

# 1 Does not set the permissions to the .ssh directory (700) or to the authorized_keys file (600). Many SSH daemons are configured in such a way that permissions must be set in such a manner, else the files are ignored. While this may work great on a home linux box, it does not work for enterprise level *nix networks. # 2 If the key is already present on the target , it will be duplicated. Again, fine for home use, but not enterprise. As others have suggested, in the very least, use ssh-copy-id. ssh-copy-id sets the permissions on the file properly if it does not exist. Unfortunately, it too will make duplicate copies if the key already exists. I don't have a '1-liner' for this one. What I do have is a 165 line function that resolves all of these issues and has a 'preview' mode. OFC, commandlinefu is not the place for such a function ;)
