Im trying to answer a question and having difficulty myself?

Question

Create hardlinks instead of copying files with rsync

Please note I cannot comment and I can only answer or Hijack answers because the sites flaws at inception.

The question is not only how do I answer but what's a good answer?

Answer 1

Commenting is a privilege that you are awarded at 50 "reputation points" (see here for more about what "reputation" is). Commenting is disabled for users with lower reputation, presumably to help weed out trolls and off-topic discussions etc. At reputation 50, it is assumed that you've learnt more of how the site works and a bit of what is expected of someone who contributes to it.

You ask about what makes a good answer. There's a section in the Help Pages entitled How do I write a good answer? that tries to answer that.

Jeff also wrote a nice Meta question-and-answer about how to write a good question, which is worth reading.

I'll disregard the rest of the question, because that looks like a separate issue that you might want to ask a new question about on the main site. Just read Jeff's Meta question about asking questions first and make sure to mention what the issue is that you are trying to solve (I can unfortunately not make out exactly what the issue is from your post above, only that a particular pipeline is not doing what you want it to do).
