mfurlend / give write access to two users

Created January 28, 2014 16:14

	sudo usermod -a -G www-data <some_user>
	Then set the correct permissions on /var/www.

	sudo chgrp -R www-data /var/www
	sudo chmod -R g+w /var/www

	Additionally, you should make the directory and all directories below it "set GID", so that all new files and directories created under /var/www are owned by the www-data group.

	sudo find /var/www -type d -exec chmod 2775 {} \;
	Find all files in /var/www and add read and write permission for owner and group:
