Match regex up to first space

Question

I have to populate a shop's images and been provided with folders of images which arein the format, eg BRL0368 Side.jpg, 5510 Dura Guard Carpet.jpg.

Now what I want to do is chop all those down so I can just try and match up in excel the part numbers eg "BRL0368.jpg", "5510.jpg"

I have something called regex renamer which takes a regex match & a replacement value - and will recurse through a folder etc and batch rename.

Unfortunately at the moment I don't have much expereince with regex so it's a bit confusing for me - I tried many different options but not having much luck.

How do I say grab the first part (alpha & digit) up to the first space and dump the rest?

this is what I have been trying ([^\s]+) - I also tried \w etc.

Answer 1

It may depend on the language used, but this should work :

/^[^\s]+/

To capture the first word and the last (the extension) you can use this expression :

/(^[^\s]+).*?(\.\w+)$/
