I just noticed the "command-line" badge next to terdon's name in the close notice for one of my questions:

And this has just made me really curious, why is it there? And what meaning does it have other than he has got it? Because I have never seen that badge... Nor a badge in a close reason...

  • FYI, in almost all cases in the SE network, you can hover over a name, tag, dates, or some specific text to get extra details. In the case of that other question, hover over the tag for more info. Or, for another example, in this question, hover over "Community♦" and it will say This question's author approved a pending duplicate vote.. – Dan Oct 23 '15 at 14:28
