  • Thanks for your reply; I'm getting closer. I'm now using this: rsync -PaSh --stats --delete -e "-i key -p XXXX" "/source/" [email protected]:/destination/ 3>&2 2>&1 1>&3 | tr [:lower:] [:upper:] > output.txt | grep -e 'bytes received' -e 'total bytes' -e files -e 'total file size:' >> output.txt which works in converting stderr to uppercase. Unfortunately I lose the ability to append stdout to the file and instead it just appears on screen. Do I need to add 1> somewhere? Commented Jan 6, 2018 at 16:44
  • @NoExpert You want to save to file the original stdout straight from the rsync command, yes? Commented Jan 6, 2018 at 17:02
  • Only one stream can go through those pipes. You can't have both the tr for the stderr and grep for the stdout in a single command. Commented Jan 6, 2018 at 17:07
  • Yes, after greping what I need, so as in my example in the original above. Thank you. EDIT: OK I've seen your updated answer now. That makes sense. I guess I'll have to live with it. Commented Jan 6, 2018 at 17:08
  • I think you can accomplish what you want if you're willing to use named pipes (FIFOs). I'll post an update to my answer. Commented Jan 6, 2018 at 20:06
