Hi all,
This one has turned out to be a bit of a tough nut to crack!
Essentially, here's what I want to do:
$ rsync --progress <some-file> ./ | awk '$0~/ /{sub(/%/,"");print $2;fflush()}'
| zenity --progress
essentially what this does, is pipe the rsync output to awk, which
strips off the '$' and prints out only the percent number, then pipes
that to zenity, so that I can get a nice progress bar.
However, it doesn't work because there is some line buffering going on,
and because rsync doesn't print any newlines (instead it prints ^M, or
carriage return) during the stage where you see
13139968 12% 11.36MB/s 0:00:08
so that it can keep going back to the beginning of the line to redraw
the progress.
So I tried to stop the line buffering by using stty
$ stty eol 0xd
which should make 0xd "end the line" according to `man stty` but it
didn't work.
I tried various other approaches, but to no avail.
When I run rsync by hand, it doesn't line buffer, but when pipe the
output to something, it does.
Is there any way around this?
Many thanks,

That's a city in Bosnia. Right?
