I'm about the closest to a command-line wizard that I know personally, but the only reason is that I grew up on the command-line - I had already graduated college before GUIs were common. I'm not entirely convinced that, in today's era, spending the time it takes to really master the command line is honestly worth it; you need to know how to do some things, but there are probably better tools for most of these jobs. A lot of what I do naturally with sed, awk, cut, paste, uniq, sort and tr could be done just as quickly and naturally in Excel; I just use the command line because I already know it.
