How does it translate?
* = 0 or more of preceding char

I have talked with Lenny Muellner from O'Reilly because I am blind and they

I want to check if in a string there are more than 3 capital letters.
I've tried using:

This match at least 3 capitals only if they are one after another.

Hi all,
I have a path to a file name. (In a script for uploading files).
I want to allow only the a-z, A-Z, and 0-9 characters and I want to replace

Can you tell me what would be this regular expression?

i don't want to just escape those characters. they were merely examples. i
