How can I delete rest of the line after a specific string?

I'm looking for a way to search for a specific string e.g. '=UUID:' and delete it and all following characters per line. I would prefer a way/macro/addon for notepad++. But all other tools or scripts are welcome :)

Before

 *://81.88.22.6/*=UUID:63969B2469B7A94EBBDBD7CB5B9C00BA
 *://*-ad.cgi*=UUID:3C8EFF48B674CC42BF5B6E2B7BA820E7
 *://*-ads/*=UUID:0D6CF7D5BE3F034C8A136CC99A074406

Note that the numbers are always different per line so you couldn't do a search 'n replace with them.

Should look like this after

*://81.88.22.6/*
*://*-ad.cgi*
*://*-ads/*

Solution 1:

Search mode regular expression, Find

=UUID:.*

Replace with nothing.

Solution 2:

It's easy. Your question:

*://81.88.22.6/*=UUID:63969B2469B7A94EBBDBD7CB5B9C00BA
*://*-ad.cgi*=UUID:3C8EFF48B674CC42BF5B6E2B7BA820E7
*://*-ads/*=UUID:0D6CF7D5BE3F034C8A136CC99A074406

My answer:

[=].*

Result:

*://81.88.22.6/*
*://*-ad.cgi*
*://*-ads/*

Explanation:

= character, represent the character you want to remove
.* characters, represent all the characters after that

That's it.
