Deleting files bigger then 20 MB

I want to delete all files that are bigger then 20MB in a folder called /var/www/cg/

I found this on google:

find / -size +2000000c 2>/dev/null -exec ls -l {} \;

I ran it in the directory /var/www/cg/ and thought it would only delete the files in the current directory but it didn't it deleted every file on the server bigger then 20 MB so I skipped it as fast as possible...

Can someone tell me how to delete files bigger then 20MB only in that certain directory?

 

find /var/www/cg/ -size +20M -exec ls -l {} \;

Code (markup):

That should list all the files over 20M

find /var/www/cg/ -size +20M -exec rm -f {} \;

Code (markup):

That should delete them, no confirmation is given.

 

Thanks a lot Tolra!
