The project fixes from the last three labs are in place. Prove it with the project's own check script, bin/check.sh. It writes its result to results/check.txt.

Read it, then try to run it:

cat bin/check.sh
bin/check.sh

It will not run yet. Once it does, its first run shows an error from the script itself, not from the project. Find the line that causes it with grep -n, fix it with nano, and run the script again.

You are done when results/check.txt ends with RESULT: ALL OK and no line says FAIL.
