I would rather bet that people don’t know that their problem has been solved for ages. Either they don’t know about the tools or can’t make the leap to think of using something like awk or sed to quickly script out their use cases. Or even quickly draft up a quick function/plugin in something like vim, emacs, sublime,…

In “The Pragmatic Programmer”, the power of unix tools and editor fluency is well argued. There are plenty of other books like “Unix Power Tools”, “Small, Sharp Software Tools”,…

My problem is always the time necessary to get good at the tool is slightly more than just brute forcing it one more time.
