Regular expressions, or ‘regex’, are sequences of characters that define search patterns, commonly used for string searching and text parsing. They are incredibly versatile and are often used to check if a string contains a certain pattern, extract substrings that match the pattern, or ...
The third group (([^\.]*)) consumes all characters after the directory, which are not a dot '.' (which is "foo" in the above example). The pattern expects a single dot (final which is ignored) and finally the fourth group (.*$), which reads until the end of the string and ...
