Regex: End of Line - how to use the expression

Regex are regular expressions that are often used in computer science. With them it is possible to describe a set of strings according to certain syntactic rules. This can help to search texts for predefined features and replace them if necessary.

How to mark "End of Line" in regex

In order to use regular expressions, it is important to know the correct syntax. In doing so, you can query the set of all numbers, characters and letters. For example, if you have a string with multiple lines, then it may be necessary to know the end of a line. Therefore, there is also a way with regex to indicate that the examination should only be done to the end of the line.
  1. In regular expressions, so-called "anchors" are not used to match a specific character.
  2. Instead, these are used to determine a specific position in a string, such as the beginning or end of a line.
  3. Mit einem Dach-Zeichen „^“ kennzeichnen Sie beispielsweise die Position vor dem ersten Character in einem String.
  4. Um das Ende eines Strings zu beschreiben, verwenden Sie das Dollar-Zeichen „$“.
  5. Wenn Sie zum Beispiel überprüfen möchten, ob eine Zeile mit einer Zahl endet, dann können Sie „\\d$“ oder „[0-9]$“ schreiben.
  6. Um zu überprüfen, ob eine Zeile dagegen mit einem bestimmten Wort wie „Bild“ endet, schreiben Sie „Bild$“.
