Delver deletes (or just finds) excess versions of files with names matching the given patterns under the control of the switches. A candidate version is excess if there are more than N valid files (where N is the keep count) and there are N valid files of the same name (not counting the version) with version numbers greater than the candidate version. As a safety feature, zero-length files are not counted by default, so writing a zero-length file (frequently a sign of an error) will not cause a subsequent delver command to eliminate a valid file. This feature can be disabled by a switch.

Switches:

As an example, the following command will delete all but 1 version of files matching the pattern "[PCedar2.0]<Delver>*". Zero-length files will be ignored, and will not count against the keep count of 1. The command responds by printing out the file names as the corresponding files are deleted, and prints a summary at the end.

Note: one must issue a command like Delver [PCedar2.0]<Delver>*>* to delete files in sun4> and sun4-o3> subdirectories or use the -r switch.
