Regex for any name

Question

I want regex with at least 2 characters start with any alphabet or any digit not matters.But It can accept - and _ . Ex : ABD , Abc_123 , 12, A-_ , A1 etc.

This is basic regex. Have a play around at [Regex101](https://regex101.com/). There is a good reference guide there to get you up and running. — garyh, Jun 14 '17 at 08:16

The difference with zipa's answer is no restriction on the third and following letters – Frank R. Jun 14 '17 at 08:24

This should do the trick:

[\w-]{2,}

But, if you want to ignore words that have special characters, you can use this:

(?<=\s|^)([\w-]{2,})(?=\s+|$)
