Package: copymon
copymon99% is pleasing only for the first hour.Copymon is a monitor of memory buffers for better estimation of copying time.It shows the most probable estimated time of copying files by monitoring Dirty-Writeback Memory stream.
It estimates the time until all the buffers are REALLY written to the disk - as opposed to most of the file managers which are showing the estimated time to writing to a buffer only.Entercopymonto start monitoring:It observes/proc/meminfowhich allows to determine ETA more precisely:MemTotal:       16343812 kB
