The ^ metacharacter is used to designate the beginning of a string (or line), and the $ metacharacter is used to designate the end of a string (or line). By adding these characters to the beginning and end of a pattern, you can force it to only match input strings that exactly match the pattern. The ^ metacharacter also has special meaning when used at the start of a character class, designated by hard braces [ ]. These are covered below.
