Hi
find -version
find (GNU findutils) 4.4.2

I issued this command to remove all files "*_original" from parent tree :
find .. iname "*_original" -delete
as you see I forgot the minus sign before iname.
The result was all regular files were deleted, just leaving behind empty directories (I don't really know why dirs remained, maybe because it is a synchronised folder with some exclusions that prevented remote deletion and the local were created back).
Is it because iname and "*_original" are both seen as EXPRESSIONS that always return true so that -delete applies to .. and content as a whole ?

Thanks
