^
- This is the negative metacharacter.
- Carrot symbol or upper pointing arrow.
- The character set is not any one of several characters.
- You add the
^ as the first character inside the set.
[/^aeiou]/ matches any one constant (non-vowel).- Another example is
/see[^mn]/ would match “seek” and “sees”, but not “seem” or “seen”.
- Does not match “see”, since there is nothing after it.
- It would match “see.” and “see “, since the full stop and space are still considered characters.
- Also works with ranges as well, for example
[^a-zA-Z]
- This negates the entire character set.
