If you use FTP from the command-line, there are two ways to get a progress indicator to monitor the progress of your transfers:
1) Before beginning the transfer, type hash. You’ll see one # symbol for every 1024 bytes transferred.
2) After the transfer has started, right-click the file in the Tracker and choose Get Info from the context menu. It’s size will be dynamically updated in the Info panel as the download progresses.
