Redirect a lot of old domains to only one new domain, in only 1 file

Dear specialists,

I need to Redirect a lot of national domainS
(as example.net + example.de example.uk example.fr)
to only one new domain
commun domain example.com
in only 1 .htassess file since I have to do this for a lot of others domains.

May I compil the lines like this:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]
RewriteCond %{HTTP_HOST} ^example.net [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]
RewriteCond %{HTTP_HOST} ^example.de [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]
RewriteCond %{HTTP_HOST} ^example.fr [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]

???

Thanks a lot for your help !!

Best Regards
