Here’s a quick and easy tool.
look is part of util-linux, and does little more than show possible variations on portions of words.
It’s probably easier to show than explain.
You can pick a dictionary file as a flag, and both cracklib and words make good options.
Best I can tell, that’s all
look does. But like so many other things, how you use it is a lot more important than what it does.
Next contender for the simplest-but-still-useful award … geoiplookup.
That’s not my real IP address, by the way. I stole that off a random web page. 😈
But in the tradition of groups and a few other one-shot, one-line tools, geoiplookup returns a general geographic location for an IP address.
I don’t know how useful that could be; after all, saying an address is located in the U.S. is only one or two steps down from saying “it’s on Planet Earth.” 🙄
Still, I can imagine this might be useful if you’re tracing Internet activity, or you want to know whose jurisdiction you’re in, according to your IP address.
But that’s about all I can think of. Perhaps there is another kung-fu master way to use this, and I just lack the insight.
