You're doing great with your scripts! Keep experimenting and practicing. Every script you write improves your skills. Don't hesitate to ask for help and keep up the fantastic work!

how would your script look like if you used printf instead of print? what would be the advantage (if any) to use printf?

That's a good question! I've never tried printf before with awk but I guess it would allow me to format the result but as the content of the file is alreay in text format print is enough in this case

wow, very nice work! (especially, because if you look at the current the latest changes for this in the repo, the condition for "For lines with fewer than 5 columns, print the last column." was taken out)

That's right!

i noticed you set initial value for sum at the end of the block - would it be better to initialise sum in another way? (regardless, your solution does print out the correct solution!)

Yes, I could have done it at the biginning like this:

awk '{ sum= 0; for(i = 3; i <= NF; i++) sum += $i; print $1, sum}' scores-table.txt

how would this script look like if used the | (pipe) ?

We would have piped it to the nl command like this:

when you look at the grep command man page, where are the grep options "positioned" compared to the parameters? (your solution works, but there may be commands where the order of the options and input(s) matters)

I agree, going to fix it by following the correct order: grep [OPTION...] PATTERNS [FILE...]

if you need to use the minimum of the options, how would your solution look like? (right now you're using 3)

I would remove the -H option and the result will still look the same

when you consider where this script (script-03.sh) is located, and where it would be executed, do you think this directory change is necessary?

It is not neccessary in this case. going to remove it.

how would you modify this script if using the command cd is not an option? (do you "need" to use cd ?)

I can make it work without cd-ing

what would the option -e mean for this script?

it specifies multiple editing commands in a single sed invocation. But is not needed in this case because there is only one command being executed.
