The action allows you to perform mathematical operations on two lists: intersection, union, subtraction and symmetric difference and save result to variable
First list, Second list
Lists for processing. The list is simple text where each line is the element of the list. For example the list of file names.
There are four operations:
•Intersection - elements that are in both lists
•Union - all elements from both lists
•Subtraction - elements from the 1st list and missing from the 2nd list (1-st list minus 2-nd list)
•Symmetric difference - the union minus intersection
The action removers duplicate elements from result
Keep result unsorted
If you want to keep the order of the elements, then turn on this switch
By default, the action is case-insensitive when comparing elements.
