Not arguing at all about being skeptical, but regarding 'cat' it's entirely possible they just had the wrong file extension on that ascii art chart. I've definitely given some plaintext files incorrect extensions if I knew I'd be wanting to open them (or quicklook them) in some program that usually ignores the correct extension.

The general vagueness of the post is a much much much stronger reason to be skeptical, imo.

Yes that's entirely possible, but my main point was that the chart looks really hand-made (by someone who doesn't really know what they're doing). I don't really see how an ascii data visualization tool would spit out such an abomination...

Exactly. Show me the command line to get that graph.

The author of the blogpost in another comment around here said he aliased csvtool to cat, hence cat'ing a csv. That said, unless there's another CLI csvtool program, the one I've read about can't plot. But there are CLI plotters out there.

Anyway, like I said, I'm not trying to say the post is factual. Just trying to point out that the fact that he cat'ed a CSV and got a plot isn't that big a deal (and shouldn't really be an indication of fraud), in a world where so many of us customize our working environments.
