What Is a Duplicate Line Remover?
A duplicate line remover scans a list, line by line, and removes any repeated entries while keeping the first occurrence of each — leaving the list in its original order, just without the repeats.
It is a fast way to clean up an email list, a set of tags, or a list of URLs that has accumulated repeated entries from being copied and merged multiple times.
