hello,

a hypothetical question... :)

say if someone deleted their www/ directory, but wanted it back as an alias etc.. for the domain-www/ directory, how would one go about creating it again?

ln -s <DIRECTORY YOU WANT TO LINK TO> <ALIAS>

So you might want to execute a command like this:

ln -s /home/sites/www.domain.com/www www

Hope this helps. :)
