04. Anchors begins and ends with

In some cases, you'll need to specify that a string starts and/or ends with certain characters. For example, if you were reading from an ouput, and had to match if it reads "success", you couldn't just write a regex that matches "success", as "not success" and "success did not occur" would also be valid matches.

Begins and Ends with

To specify that a string should strictly start or end with certain character, we can use the hat (^) or dollar sign ($).

^zip
Match all strings that start with zip.
zip$
Match all strings that end with zip.
^z..i.p$
Match all strings that start with z, has any two characters then an i, then another character, and ends with p.
