So sort banana is correct and uniq is correct. Notice when you sort banana there is a blank space in the file. Thus wc -l (count lines) will give the wrong answer, but wc -w (count words) should work.

@JosephWhite Thanks for the explanation. I’ve just done the exercise challenge and did this command “sort banana | uniq -c”. Of course, it will sort and list the words but not mention how many unique words are listed. :slight_smile:. I had to cound them. And of course, if you have a long list, it will be impractical to use that command.
