- Selects information about the core segments with the specified name.
- [-panic-time <MM/DD/YYYY HH:MM:SS>] - Time of Panic That Generated Core
- Selects information about the core segments that were generated by a panic at the specified time.
- [-size <text>] - Size of Core Segment (bytes)
- Selects information about the core segments that are of the specified size.
- [-panic-string <text>] - Panic String of Panic That Generated Core
- Selects information about the core segments that match the specified panic string.
