When I use wget to download a large file, it gives me "56M/s". I want to know if it means 56 megabits per second or 56 megabytes per second. Thanks!
231,997,440 61.4M/s in 4.0s
It's megaBytes. Apart from anything else, if you divide the file length (231997440 bytes) by the time (4.0s) you get the same answer (give or take).
Edit: if you merely want to set the text output for the rate, so it displays eg "MB" instead of just "M", it's free software, you can always recompile it yourself. But it may be worth checking if there's a newer version of wget, since both mine (1.11.4 and 1.12) seem to display the B:
The output shown is in Megabytes/second you may also see Kilobytes/second and I guess but very unlikely bytes/second.
If you want to rate limit the download to a specific spped you can use the
--rate-limit=56M will limit the download to 56Mb/s.
