sudo cat idenityfile.rsa > authorized_keys
-bash: authorized_keys: Permission denied

if I su - to the user then I can do this but why can I not do this with sudo from my user?

    The > redirection does not work like this with sudo.

    You can use these alternative:

    sudo sh -c 'cat idenityfile.rsa > authorized_keys'

  2. It is because the redirect isn't "sudo"ed Try something like this instead:

    sudo bash -c “cat idenityfile.rsa > authorized_keys”
