I am wishing to run rsync from a cron job, but this rrthis this fails as rsync is configured to use the SSH shell, and SSH, even though I have setup keys (ssh-keygen) with empty passprases, still wants an ENTER KEY to proceed. I don't know how to make cron submit a blank ENTER. But, according to posts I find, SSH should work without a password, including NUL ENTER.
This is my script:
Sudo rsync -e ssh -azv /home/rrider/testfiles
