Need RewriteRule to redirect my blog to another

[ElMobd3]

Hi all,
I have a blog which its url is ***.com/link/
It's a WordPress.
then I changed the url to ***.com/blog/ so I need a RewriteRule to redirect links like that:
***.com/link/?p=21 to ***.com/blog/?p=21

I tried that RewriteRule
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(?p=[0-9]+)$ mysite.com/blog/?p=$1
but I get an error.
I hope you can help me.

That's a rewrite.

You'll need a redirect. The target will need the protocol and domain name added. You'll need the [R=301,L] flags.

RewriteRule cannot see query string data, so you'll need a preceding RewriteCond looking at QUERY_STRING.

RewriteRule will need to look for a request containing "link" or "link/index.php" for best operation.

Thanks for your reply.
Sorry I'm not good in writing rewriteRules and now I have another content at "link" so I need a specific rewrite or RewriteRule that enables URLs like "***.com/link/?p=21" redirect to "***.com/blog/?p=21" the 21 here meaning all numbers.

Following g1smd's advice above, and consulting the mod_rewrite documentation, you'd get something like this:

Options +FollowSymLinks
RewriteEngine on
#
RewriteCond %{QUERY_STRING} ^p=[0-9]+)$
RewriteRule ^link/?$ http://mysite.com/blog/?p=%1

Please see the Apache mod_rewrite documentation and the regular-expressions tutorial cited in our Apache Forum Charter for more information, as well as tips on how to get the most from this forum.
