Unless a repo consisted of several independent projects, it seems it would be simplest to just have one
.gitignore file at the root of the repo than various ones throughout. Is there a standard best practice on this or some analysis online of when one approach is better than the other?
I can think of at least two situations where you would want to have multiple
.gitignore files in different (sub)directories.
Different directories have different types of file to ignore. For example the
.gitignorein the top directory of your project ignores generated programs, while
Documentation/.gitignoreignores generated documentation.
Ignore given files only in given (sub)directory (you can use
Please remember that patterns in
.gitignore file apply recursively to the (sub)directory the file is in and all its subdirectories, unless pattern contains ‘/’ (so e.g. pattern
name applies to any file named
name in given directory and all its subdirectories, while
/name applies to file with this name only in given directory).
