From the beginning of computing there has been a problem with bootstrapping knowledge… the person creating a tool gives it a name, and describes it, but knowing that someone solved the problem you have and what the name of that tool was always a challenge.

But that is nothing new… you posted in English but if you were to learn a different language you would have a very similar problem, and one of the most universal strategies for making that transition is to drill on vocabulary. Once you have built a small vocabulary then you can expand it using a dictionary.

The real message behind someone saying RTFM is that there are so many educational and search resources now that asking some rando on the Internet to rewrite a Howto on the fly is lazy. Simply typing the exact same question into Google will bring up a kickstarter set of vocabulary and resources. If you actually do this your question will often answer itself, and if it doesn’t and you start by pointing out why your efforts failed to help you with your specific problem and use the vocabulary (at least briefly) that your research turned up to guide the reader toward where your problem is, you should get less RTFM responses.

You must be off by a decade. Your reference mentions no OS and Unic was developed around 1970.

If you are invested in Windows software… don’t run Linux. Being able to run Windows software is like a “patch” to get you by until you find a Linux equivalent. Pretending you can have your cake and eat it too will just leave you disappointed.

Linux has amazing software… but in most cases it feels very different from Windows. If you learn why it is different then you may start to appreciate Linux for what it gives you rather than what it takes from you.
