I've been doing some large copies using cp and sometimes annoying the sys admins around here by using large amounts of network bandwidth. nice does not make any significant impact especially as I'm often running cp on a PC with nothing much else running.

Can I request that a throttle option is added to cp to allow the copy process to proceed more slowly and hence use less network bandwidth,

Personally I don't think such options should be in each tool, since by its nature this is a global resource sharing problem, and thus the options/logic are better in locations with broader scope.

Now there are such options in some commands, including rsync, which might handle this case for you.

thanks, Pádraig.
