Regex: How to remove last characters

[mactron]

I would like to remove last three characters and save first six characters in new variable.

2ef322ree

I have tried the code below, but that's the opposite of what I'm trying to do.

.(3)$

Here is the output in variable:

ree

Any suggestion? Thanks!

string line = "2ef322ree";
return line.Substring(0, line.Length - 3);

or

project.Variables["line"].Value = project.Variables["line"].Value.Substring(0, project.Variables["line"].Value.Length - 3);

or

string line = project.Variables["line"].Value;
project.Variables["line"].Value  = line.Substring(0, line.Length - 3);

This code works... May I ask you how to add variable instead of 2ef322ree? Thanks!

string line = "2ef322ree";
return line.Substring(0, line.Length - 3);

Also, you can do it with the standard action, see the screenshot below:

What to search - .{3}$
What to replace with - leave empty
