The progress of all open files and 1.5 +file systems can be monitored. If run as a regular user, the set of open files 1.6 +will be limited to those in that user's processes (which is generally all that 1.7 +is of interest to the user). In any case, the selection of which files to 1.8 +display is possible through a wide assortment of options. As with top, the 1.9 +items are displayed in order from most to least active. 1.10 + 1.11 +The interface extends beyond the traditional capabilities and expectations of 1.12 +console applications. For instance, ftop supports two output modes, full (using 1.13 +ncurses) and limited (simple plain text). The output mode can be specified at 1.14 +invocation, or changed dynamically as the program runs. Limited output mode is 1.15 +well suited for piping into other utilities (such as grep or sed) or simply for 1.16 +redirecting into a file. Full output mode is much more visually appealing and 1.17 +contains a few more features. Keyboard control and interaction is not limited 1.18 +to full output mode; it is also available in limited output mode. 1.19 + 1.20 +As another unique usability feature, the command line options for ftop exactly 1.21 +match the run-time keyboard commands. In other words, the '-p' command line 1.22 +option can be used to specify a list of processes at invocation, and while ftop 1.23 +is running, 'p' can be pressed to modify the list. As another example, '-h' 1.24 +will show the help screen when ftop starts, or 'h' can be pressed at any time 1.25 +afterward to show the help screen. This commonality exists for every 1.26 +configuration option. And the current value for all options can be viewed at a 1.27 +glance in the options screen. 1.28 + 1.29 +Finally, ftop can also be easily configured to display additional files that 1.30 +are not currently open by any local processes, and file system usage. If an NFS 1.31 +client is writing a file on a local export, that file may not be open by any 1.32 +local process, so the additional files feature is used to display those files. 1.33 +One or more file systems can be monitored if many files are being created, for 1.34 +instance while restoring from a backup or extracting a large archive. 1.35 + 1.36 +Ftop has many more features than those described here. Detailed online help 1.37 +describes all available functionality, and provides examples of some of the 1.38 +interesting ways in which ftop can be used. 1.39 + 1.40 +Ftop currently makes use of the entries for each process in /proc/PID/fdinfo/ 1.41 +to determine the file position and other details.
