Purge? Delete? Duplicate entities

[trinkit]

A co-worker asked me this question and I am stumped because I rarely use it. In fact, I don't think I've ever used it. Years ago there was a command (and the name of it escapes me right now) that would delete/purge duplicate entities/lines (or whatever) on the same layer. It was used to clean-up drawings and reduce the file size. Does anyone know what this command might be?

Thank you.

From the Express Tools:
OVERKILL
Removes unneeded objects by deleting duplicates and combining line and arc segments that overlap.

Command: OVERKILL
Select objects: Use a selection method to select annotation objects


OVERKILL removes objects whose geometry is redundant. For example:

Duplicate copies of objects are deleted
An arc drawn directly over a portion of a circle so that the arc cannot be seen is deleted.
Two lines drawn at the same angle so that they partially overlap are combined to form a single line.
Duplicate line and/or arc segments within polylines are removed.
