"Thank you" answers:
Rather than adding a separate "Thank you", upvote the answer(s) that helped you, and consider ["accepting" the answer](https://unix.stackexchange.com/help/someone-answers) that was the most helpful in resolving your issue.  These are the best ways of showing gratitude on this site.  Accepting an answer not only marks the question as resolved, but also signals to _future readers_ that the accepted answer actually solved the issue.  More information about this is available here: https://unix.stackexchange.com/help/someone-answers
