| Description |
calculates a hexadecimal "checksum" for a specified attribute, or the entire item if no attribute is specified, and produces result as a list.
The checksum statistics change whenever a file is updated, which provides a means of determining if a file has been changed. When an "itemlist" is specified, statistics are calculated only for the selected item-ids. If not specified, the entire file is used. If an "attr.name"is specified, statistics are generated only for the attribute name or number specified. If "attr.name" is not used, or if the specified attribute number is 9999, the entire item is used. The attribute mark trailing the specified attribute (or item) is included in the statistics. To use checksum statistics, "check-sum" all files, or portions of files to be verified and record the output statistics. At a later time, repeat the check-sum process. To verify that the files have not changed, manually compare the two checksums. |
