I need help with a regex to strip series of numbers and letters follwing # from titles. e.g. #8545 or #8545-AFT etc., these characters can be anywhere in the beginning, end or middle of my title

e.g. "my title is #8545" or "#8545 listed here" or "listed #8545 here" - I want anything following # stripped upto 4,5,6,7 characters.

Title =~ s/

Thanks
