What does RTFS stand for?

Read the flippin’ source

RTFS is a slang term that originated from the world of computer programming. It is an acronym that stands for “Read The Source File”. It’s a way of telling someone that they can find answers to their queries in the source code of a program itself. This is especially useful if the code is well-commented, meaning there are notes explaining what certain parts of the code do.

For instance, let’s say an entry-level coder, Sam, asks you a question about a piece of software you made. If you know that the answer is easy to locate in the code, you might respond with, “RTFS! You’ll find what you’re looking for right there.”

Using RTFS is pretty straightforward and it is typically used in a friendly or joking manner. However, it’s important to note that some people might use it out of frustration or due to a lack of time to explain things in detail. So, don’t be surprised if you come across it in a less than cheerful context.
