Copying just one attribute to all products

Probably this has been answered before, sorry about that.
I created an option name, value and settings (including price and weight) for an attribute.
I did it on just one product to test how it looked.
I like it and would need to copy just that one attribute to all products.
Products have different option names and values, but that new attribute is unique, inasmuch that new option name only exists for that one test product.
How do I do that?
I already fiddled with the global copiers in Option Names Manager, Option Values Manager, and Attributes Controller, they don't throw errors but when I look at products I don't see the new option.
Thanks.

How are you trying to do the copy?

You should be able to just look at the Product with the 1 attribute and then copy it to a Category of products or another Product ...

Thanks for reply, Ajeh.
Yes, I can do that but that would copy all the attributes of the product, and it has other option name-value pairs.
Are you suggesting to create a test product with that just one pair and copy that attribute globally?

Make a temp product with the one attribute and use it for the copy ... :smile:

Thanks for answer, Ajeh, I understood that already.
Make sure that people select the ignore option, I just wiped out all other attributes because of haste and will have to restore from backup.

eeeks!! :eek:

And naturally one always makes a nice, fresh backup prior to doing nasty things to the database ... :cool:
