I thought -c was for creating a new archive?

I believe `tar -u` is correct, but I also remember that `tar -x` is for extracting files, so that one is definitely not it.

I’m a bit confused; I thought `tar -c` was for creating archives, but I can't remember what `tar -t` does.

I think the command we're looking for is the one that updates the archive, which might be `tar -u`, but I'm not completely sure.

I remember practicing with similar questions, and I feel like `tar -u` was the one that appends files if they are newer.

I'm a bit confused by this question. The options don't seem to directly align with my understanding of product backlog refinement. I'll have to review my notes to make sure I'm interpreting this correctly.

This question feels familiar. Didn't we have a similar example regarding data modeling principles? I want to say it leans towards C, but I'm not entirely confident.

Whitespace is the correct answer. Bash for loops use whitespace to identify the individual items in the list they're iterating over.
