.htaccess Help needed

Hi

I want to redirect a url in htaccess file. here's what I want to do:

changing:

to:

(means I want to remove category ID)


would you help me plase to do that?


P.S.
I have some traffic by some urls in the 1st format. Don't want to loose them. In my site I can use the 2nd format, but want to redirect the 1st one to the new url first.

 

A 301 redirect lets search engines know where you've moved your page to
it basically says "hey... search engine, I'm over here now, so can you let the PR flow this way and don't penalise me since it's not duplicate content"

The modern way of doind a 301 redirect is to do it with your htaccess file
(this will only work with apache servers)

There are lots other ways of doing a 301 redirect, have a look here:

Thanks "ForumSeeder", but I'm using a htaccess file to redirect many urls. I Just think one url is not fine, although I have traffic by it. so I want to remove an ID in urls because it's not necessary.
I use this:

RewriteRule ^articles/?/([0-9]+)/?/([_A-Za-z0-9-]+)/?$ list.php?id=$1 [L]

Now, what if I remove the ?/([0-9]+)/? (this is category ID)

So the new one will be:
RewriteRule ^articles/([_A-Za-z0-9-]+)$ list.php?category=$1 [L]

My question is how to change urls in 1st format to 2nd one?

Is it work fine for this?
