Almost. Your code is giving each player's second score. However the question asks for the last score. Leila only has one score, so you need something slightly different.

I have made changes

This sh file could work if it were run in the helper-files directory. However if I run it from here (the cat folder) it doesn't work. How would you make it work from here?

I fixed it. it now runs from the cat directory, may you please chack it for me

Again, this would work if run from the right folder, but in general it's best to make sh files run from where they are in the checkout structure, or from a clearly defined location identified in a comment in the file (e.g. Module-Tools).

This needs the same relative path fix as the previous two comments, but otherwise looks good

i fixed it

There's a very subtle problem with this. Hints:

1. What does set -euo pipefail do?
2. What does grep -c return when there are no matches?

That's quite subtle!

There is also a simpler way to do this without a for loop!

the set -euo pipefail is just for good practice. the e is to ensure the script exists immediately if a command fails, the u causes the script to exit immediately if you try to use an unset variable and the o catches errors in a pipeline. I tried the other way under the original. It is a lot easier, thank you

Well done, perfect score for sed

This has the same relative path problem we had in cat, but is otherwise correct
