With multi line mode, also matches right after a new. Matching the End of StringĪs we mentioned earlier, we can use the dollar anchor in a regex to denote the position after the last character in a given string. and are zero width regular expression anchors that match the beginning or end of the matched string. Our article on how to use the starts with regex and does a great job of explaining it. The caret ”^” is another anchor that denotes the beginning of a string. A regular expression (shortened as regex or regexp sometimes referred to as rational expression) is a sequence of characters that specifies a match pattern in text. Now that we know what the anchor ”$” means, let’s see how to use it to match the end of a string. “*“ is a quantifier that indicates any number of times.

Then, we are going to explain using examples how to match the end of a string. In order to match an empty line (multi-line on ), a caret is used next to a which is another anchor character representing the position at the end of line ( Anchor Characters: Dollar () ). In this short tutorial, we are going to shed light on how to use the regex “ends with” to match the last part of a string.įirst, we will start with a few insights into what the anchor $ means. Another typical use case for caret is matching empty lines (or an empty string if the multi-line modifier is turned off).
