Redirect old url to new url by cuting some word

[DooDoo]

I just change all url in my website around 2000 url.

The pattern of old url have fix pattern such as www.example.com/book-XXXXXXXX.html

where book- is fix and XXXXXXXX is variable.

I change the new url by delete fixing word book-.

so www.example.com/book-XXXXXXXX.html is changed to www.example.com/XXXXXXXX.html

Anyone please kindly advise how to write in .htaccess to redirect all old url to new url.

I have try 2 times as follows but it does not work.

RewriteCond http://www.example.com/book-^(.*)$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

RewriteCond http://www.example.com/book-(.*) [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

Many thanks in advance.

Try

RewriteRule ^book\-(.*)$ /$1 [R=301,L]

without any RewriteCond

I tried doing a 301, too but it resulted in not being able to access my site at all. I'd like the 301 to make the old files redirect to the new ones.

Did you remove the RewriteCond like abduraooft suggested? Your original RewriteCond is missing the variable to test against. See the example in the top-right of the mod_rewrite cheat sheet.

Yes, I did and it work now. A little problem is some url that have book-book-XXXXX.html will have double redirect.

I am very new on mod-rewrite , if you have any more suggestion please kindly advise.

RewriteCond , It has many variable, which one should I use it ?

%{REQUEST_FILENAME} or any one.
