regex don't capture 1st character

Question

I want to capture every letter except the first letter in the string.
Example string: The cat in the hat.

I know to capture the first letter is /[^]/ so I would want something like /not [^]/

Answer 1

You can utilize a capture group with a basic regular expression.

^.(.*)

The capture group stores the match result ignoring the first character in the string.

Answer 2

Use a zero width positive lookbehind:

(?<=^.).*
