Basically lifted straight from https://mywiki.wooledge.org/XyProblem https://mywiki.wooledge.org/XyProblem. GreyCat's wiki is the best Bash resource in existence, but the first example is pretty typical for the IRC channel. There's really no reason to berate people. For example, lots of people have never or very rarely been exposed to anything other than three letter extensions (including most DOS/Windows users), and it's entirely possible that they were trying to do something which only involved three letter extensions. Not every script needs to be a completely generic solution.
