Many people are surprised to learn that `sed`, a seemingly simple text filtering program, is actually Turing complete. This realization prompts the question: how can a text processing utility achieve such computational power? The answer lies in sed's fundamental operations. Essentially, sed functions as a miniature...
Like almost all rules, there are cases where breaking them is a good idea and seasoned writers may well object with "but" responses for some of these. Thus, consider the rules below as mental rumble strips - you should probably slow down and think if you encounter these cases.
Git only tracks files, not directories. It will only create a directory if it contains a tracked file. But sometimes you need to “track” a directory, to ensure it exists for fresh clones of a repository. For example, you might need an output directory called build.
