Help Needed With .htaccess RewriteRule

[AdeLewis]

Hello Fellow Mozzers,

I would really appreciate a little help as I have been banging my head against a wall for the last few hours trying to create a .htaccess RewriteRule.

I have around 300 URLs that I need to 301 redirect following a site re-build, they are in groups of similar urls but infortunately not broken down in to folders.

Here is an example of a few URLs:-

https://www.domain.co.uk/chamaecyparis-lawsoniana-ellwoodii_2.htm
https://www.domain.co.uk/chamaecyparis-lawsoniana-ellwoodii-200225cm-6670.htm
https://www.domain.co.uk/chamaecyparis-lawsoniana-ellwoodii.htm
https://www.domain.co.uk/chamaecyparis-lawsoniana-ellwoods-gold.htm
https://www.domain.co.uk/chamaecyparis-lawsoniana-lemon-queen.htm
https://www.domain.co.uk/chamaecyparis-lawsoniana-yvonne-200cm-66.htm

All of the above URLs need to redirect to a new URL:-

http://www.domain.co.uk/chamaecyparis-lawsoniana

Here is the RewriteRule that I currently have but it isn't working:-

RewriteEngine On
RewriteRule ^(.*)_chamaecyparis-lawsoniana$ https://www.domain.co.uk/chamaecyparis-lawsoniana [R=301,L]

Anyone have any suggestions?

Thanks
Ade.

Thanks Jaspal, works perfectly.

Yes we did meet at LinkLove and hopefully will do again at the next one as I now owe you a beer!

Much appreciated.
Ade.

Hi Ade, didn't we meet up at LinkLove? Hope things are going well.

Try this:

RewriteRule ^chamaecyparis-lawsoniana-.+ https://www.domain.co.uk/chamaecyparis-lawsoniana [R=301,L]

The underscore was a problem as was the $ at the end

using -.+ at the end to avoid matching the target url

I tried that with regexr and it seems to work ok, not used it in an htaccess
