Due to the fact that the * character can be used to match all characters in a filename, or all files in a directory, it is referred to as a metacharacter

"Wildcard " seems to be the correct choice.

Explanation:

A metacharacter would be any character with a particular relevance, including a carat (^), a dollar sign ($) as well as an asterisk (*).It is different compared to something like the wildcard metacharacter. This same character developers have been using alone would be a period or perhaps a dot. With the exception of a new line it compares another other character.
