Hi people !
I need help regarding deletion of groups.
I have an obj that comes in with hundreds of irelevant groups.
So I've made my own groups.
And now I want to delete the junk groups that I don't need.
I figured that GroupDelete is the operator I need.
I can't figure out how to isolate the string to delete any other groups except those that end with “_grp”.
Thanks in advance.

You almost had it. Include the wildcard before the exclusion.

* ^*_grp

Oh you boss ! Thanks alot !
