I tried to do this myself, but I am a newbie with regex.

I have this URL:

http://[DOMAIN]/[category]/27466-some-article-is-here

Which should redirect to this URL: 

http://[DOMAIN]/[category]/some-article-is-here

I simply want to remove the ID from the URL. The category could be anything, which I want to keep.

How do I achieve this?

UPDATE: I adjusted the Redirect from @taduuda to this:

RewriteRule ^(.*)\/[\d]*\-(.*)$ $1/$

This looks good with a testing tool, but this still doesn't work on my wordpress site.

My htaccess:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# BEGIN - Custom Redirects
RedirectMatch 301 /heute(.*) /$1
RewriteRule ^(.*)\/[\d]*\-(.*)$ $1/$2
# END - Custom Redirects

RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

</IfModule>
# END WordPress

Not sure if this will work with every URL you have, but this whould give you a base to work off of. Note that this sepcifically checks for 5 digit IDs. If you want this to be more flexible, simply change {5} to a different quatifier like *. Also note that this might match URLs you don't want to redirect.

* Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)

Your rule:

RewriteEngine on
RedirectMatch 301 ^(.*)\/[\d]{5}\-(.*)$ $1/$2

Or a more precise variant to avoid unwanted redirects:

RewriteEngine on
RedirectMatch 301 ^(.*example\.com\/.+)(?:\/[\d]{5})\-(.*)$ $1/$2

Since you mentioned that you're new to regex, here are some tools that will help you get started:

  • Thanks for your help. Unfortunately this didn't work properly, even as I was changing it a bit. I used `RewriteRule ^(.*)\/[\d]*\-(.*)$ $1/$2`, which looks right with the testing tool, but doesn't work on my site. Any suggestions? – NILL Feb 26 '18 at 09:34
  • The regex does not seem to be the problem then. A few questions: Where are you trying to implement the .htaccess? Are your sure your webserver allows to change settins via .htaccess? And, since you are using Wordpress, have you tried changing the [settings for the permalinks in Wordpress](https://codex.wordpress.org/Settings_Permalinks_Screen) itself ? – cetteup Feb 26 '18 at 10:08
  • I added the redirects to the .htaccess in root. I already did another redirect, which was working. And changing the settings for permalinks is no option, because we are transfering the site from Joomla to WordPress and the Joomla-IDs don't match the WordPress-IDs – NILL Feb 26 '18 at 10:16
  • Could you add the content of your .htaccess to your question? The two redirects might be interfering with oneanother. – cetteup Feb 26 '18 at 10:18
  • My bad, you'd need to use redirect rather than rewrite. Try setting it up with my edited answer. – cetteup Feb 26 '18 at 11:55
