software recommendation - Is there any utility like the Windows program smartcopy?

It should help me pause copying, so I dont have to wait for each copy to finish. Basic googling didnt help out. The windows equivalent is Teracopy, or Fastcopy.

I need the application to be GUI based, but wouldn't mind shell commands.

I wait for the copy to finish, in cases where I copy to the same destination, like a pen-drive, where throughput is in the order of 5 MB/s.
