Thank you for your response. I really don't understand why I get this error:
home@laptop:~$ rsync --rsync-path='sudo rsync' -av firstname.lastname@example.org:ali.txt /home
sudo: sorry, you must have a tty to run sudo
protocol version mismatch -- is your shell clean?
(see the rsync man page for an explanation)
rsync error: protocol incompatibility (code 2) at compat.c(174) [Receiver=3.0.8]
