Basic habit to get into:
If you’re contemplating doing something destructive, do a dry-run first.
In this case, remove the -delete flag, run the command and see what you get.
A good approach is to build a command step by step and test your assumptions each iteration.
Things might take a few moments longer, but one day it’s going to save your bacon.
As for unexpected globbing, learn the difference between quoted and unquoted, and single versus double quotes.
