Exactly. I insisted so you are clear about the difference between exact and sloppy phrasing.

Excellent! What are the conclusions?

So to summarize

1. I'm kinda at a loss here. The answer is probably super simple, but I just don't get it. Could it be only 1 time. Since we don't reach that part anymore because there's no loop for it?

Shouldn't it read 15 items PLUS one EOF? The question was "How often executed", no?

Quote:

2. 15 times.
3. 8 times, since we only reach grep r, when there's no "s" in a file name.
4. 2 times, since there are only 2 items with neither "s" or "r"
5. 1 time.

Closer. Here some approaches from my side:

Code:

ls | ../shscr |& grep  "+ grep" | sort | uniq -c
      9 + grep r
     15 + grep s

Code:

ls | ../shscr |& grep "+ echo [A-Z]" | sort | uniq -c | grep -o "^.*echo" | sort | uniq -c
      6       1 + echo           contains an "s"
      9       2 + echo           doesn't contain "s"

Code:

ls | ../shscr |& grep -o "+ let" | sort | uniq -c
      2 + let
