The "-size" option gives summary disk usage information for a set of Vision files.
vutil -size [ -n ] [ -q ] [ files ]
-n Show all files.
-q Exit if user interaction is required.
Without files, standard input is read. The printed information includes the total size of the file, the number of records, and the number of deleted records the file contains. It also includes the percentage of records in the file which are not deleted records. This information is useful when you are trying to find candidate files for rebuilding when disk space gets tight. Non-Vision files are ignored by this command.
