I can't tell what you're trying to do here, so it's hard to say what to suggest. However, a couple of things stand out.

        @results = $each_line;
        %hashTemp = map { @results => 1 } @results;

The first line there is trying to put a scalar into an array. You'll have an array with one element, which may not be what you want. If you want to add to the array, look at push and unshift.

The second line seems to be trying to get the unique elements from @results, but the map block is wrong for that.

This may be what you're shooting for:

        push @results, $each_line;
        %hashTemp = map { $_ => 1 } @results;

However, I'm guessing that everything after the push should be outside the for loop, and maybe outside sub edits. That depends on what you're ultimately trying to accomplish.

Also, I think sub edits() could be sub edits. The former creates a sub with a prototype, and you probably don't want that.

Finally, I think it would be a really good idea to use strict and warnings.
