I have many subfolders in my repo, in which there are few build/ directories I'd like to ignore when committing my code. As I understand it, there are two ways to ignore all of the folders:
*/build/(Unix wildcards)build/(git way of ignoring files/folders)
I've found Git ignore sub folders but it has two answers and I would like to know what the difference (none?) between the two approaches is. Does the same rule apply to files?
build/ is the right way to do it. It will ignore any files that are inside build directories no matter how deep are these directories nested in your repo.
*/build/ means ignore build directories that are exactly one level deep inside your repo. So for instance files inside build and foo/bar/build won't be ignored.
If you need more fine grained control, you can always add specific directories to exclude but also not to exclude using ! as a prefix.
