delcat [ parameter=value ... ]
Parameters are: tape_label, pass_number, satellite, start_time, confirm_each.
delcat deletes records from the archive pass catalog. Records to delete can be identified using any combination of the following criteria: tape label, position of pass on tape, satellite name, and start time. These criteria were chosen to make it easy to delete
- catalog records for all data on a tape - the catalog record for a specific pass on a tape - duplicate catalog records for a particular pass - catalog records for passes on unknown tapes
Candidate records can be shown to the user to confirm each deletion. No candidate records are deleted until each has been examined. Pressing the break key during confirmation halts the function and causes no records to be deleted.
Note that catalog records are not actually deleted; they are simply marked internally as deleted. The packcat function can be used to physically remoted records marked as deleted. It is recommended that packcat be used sparingly.
