when doing an
rsync -P <source> <destination> it will output transfer speed during the copy, updating every 1 second I believe. But it happens on a single line. How can I save all that text output such that I can plot the transfer speed over time and see what has happened?
I am troubleshooting and moving a 100gb file over X minutes, for a while it bursts at 400 MB/sec, sometimes will drop down to KB/sec; I want to know what happened over those X minutes of transfer how it behaved... Like in Microsoft Windows the popup window that happens during a copy you can visually see highs and lows of the transfer speed.
