How do you search and replace anything beyond an equal sign

Question

We have a property file (name, value key pairs) and would like to replace everything beyond the equal sign = with nothing. How do I do that?

label.one=One
label.two=Two

Post replacement, I would want

label.one=
label.two=

Answer 1

With a regexp: replace =.*$ by = (with CTRL-F and regexp checked)
