netcat-tar-pipe.sh

# should be faster than rsync

# 1. receiver
nc -l 6001 | tar xvpP
# 2. sender
tar cPf - /etc/profile.d | nc ${HOST} 6001

rsync-netcat.sh

# Here is an example using the debian/ubuntu version of nc (using named pipe as described in nc(1) because nc doesn’t have -e or -c)

# receiver
rm -f /tmp/rsyncpipe && mkfifo /tmp/rsyncpipe && cat /tmp/rsyncpipe | (read cmd && eval "$cmd") | nc -l 1243 >/tmp/rsyncpipe

# sender
rsync --progress --rsh='bash -c "(echo ""$@""; cat) | nc $0 1243"' <file> 10.142.0.119:<file>

# Unfortunately, due to the fifo, rsync stays open even after the transfer is complete, so you have to Ctrl+C on both sides when it looks like it’s done (when --progress reports to-check=0/n).

rsync.sh

# favorite rsync syntax, optimized for speed.
# rsync-path/sudo part is if you don't have read permissions, requires passwordless sudo I would assume.
# can use following script to find fasted ssh cipher https://gist.github.com/dlenski/e42a08fa27e97b0dbb0c0024c99a8bc4
