Open File Monitoring
Ftop is to files what top is to processes. The progress of all open files and file systems can be monitored. If run as a regular user, the set of open files will be limited to those in that user's processes (which is generally all that is of interest to the user). In any case, the selection of which files to display is possible through a wide assortment of options. As with top, the items are displayed in order from most to least active.
