Need help with Regex

[avi]

I need to find some text, no matter what, but that has a space at the end. How do I write this in Regex?
Thanks!

Simple way is like this:

abc[ ]

The brackets with a space inside represent one blank character.

FYI, a good site to simulate and test out regex expressions can be found at:

Thanks, but the link is broken.

Just tried it here, worked fine.

Make sure you refresh the page, I made one edit to the link 30 seconds after my post, maybe you were too fast for me...
