No, I don't know what are inodes. But /usr/local/apache/domlogs/account/account.com don't appear to be a symbolic link or anything. Looks like a regular folder with access log in it being updated live.
so is it normal? and what is the use of it? Thanks.
Try a ls -i on both files and you will see the same number appear, meaning they have the same inode, so they are the same file. An update on this inode will thus change the two files at the same time (if you can really speak of two files)
user@server [/usr/local/apache/domlogs]# ls -i yourdomain.com 316698 yourdomain.com
user@server [/usr/local/apache/domlogs/account]# ls -i yourdomain.com 316698 yourdomain.com
