File transfer performance display?

[Derek Atkins]

Hey BLUers,

I used to be able to use curl to download some information, and it
gives me some really nice transfer rate properties.  Unfortunately I
can't use that method anymore.  So now I've got a process that
effectively is:

  ssh host run-program > localfile

Unfortunately this doesn't give me any feedback about my download
transfer rate.  I found a program called cstream, so using that I can
do something like:

  ssh host run-program | cstream -T 5 -o localfile

This gives me output that looks like:

...
132222700 B 126.1 MB 826.4 s (13:46 min) 159991 B/s 156.24 KB/s
132711520 B 126.6 MB 831.5 s (13:51 min) 159600 B/s 155.86 KB/s
133505134 B 127.3 MB 836.6 s (13:56 min) 159589 B/s 155.85 KB/s
...

This is the information I want, however it's output on
consecutive lines.  So at 5 second intervals over an hour
it will output 720 status lines.  That fills up my terminal
buffer pretty quickly.

What I'd really like is something like the old curl (or scp)
output that keeps the input on a single line.  Does anyone
have any suggestions for what program I can use?  Neither dd nor
cat provide throughput information, and I can't get scp, curl, or
wget to copy from stdin to an output file and give me throughput
information.

I'd prefer not to have to go hack the cstream sources if I could
avoid it.  Is there any ready-made tool that could do what I want?

Thanks,

-derek
