How do I match a pattern (in my case it's new line character) but not when it's on the very beginning of the string.

So I need something like /\n/ but matching only second and third new line characters in the following string \nthis is a line\nand the second one\nand the third one

Just add a `(?!^)` or `(?<!^)` before `\n`. – Wiktor Stribiżew Apr 05 '17 at 12:22
It depends on the language you are ultimately using... – l'L'l Apr 05 '17 at 12:23
