Correct! It distinguishes Doctor lines from usual lines just having "Doctor" in it

What will happen if I try to execute the script with ls % part?
There was a problem hiding this comment.
it gives me this:
cyf@MacBookPro ls % ls % ls -1t child-directory
ls: -1t: No such file or directory
ls: %: No such file or directory
ls: ls: No such file or directory
child-directory:
helper-1.txt helper-2.txt helper-3.txt

What will happen when we pass -h command line argument? Is it what we want to achieve in this task?

-h hides the file name
the correct one is -l to show the file names and i fixed it ,thanks

runs once per line
this way is good to do with several columns but i made it simpler ,thanks
| # TODO: Write a command to output just the names of each player along with the total of adding all of that player's scores. | ||
| # Your output should contain 6 lines, each with one word and one number on it. | ||
| # The first line should be "Ahmed 15". The second line should be "Basia 37" | ||
| awk '{sum=0; for(i=3;i<=NF;i++) sum += $i; print $1, sum}' scores-table.txt |
