giving read and write access to group and folder

Question

Say I have a group called mygroup and I want it to have a permission of rwx (777) to the folder /var/www . How do I do this? What is the appropriate command to do this in ubuntu?

Answer 1

sudo chmod 777 /var/www

The sudo part of the command is just providing super user access. This needs to be run from a terminal session.

sudo chmod 777 /var/www -R

will apply to all files and sub folders recursively, underneath /var/www

Answer 2

chgrp -R mygroup /var/www
chmod -R g+rwxs /var/www

CAUTION: This will overwrite your group ownership and permissions of all files under /var/www.

The 'g' will cause newly-created files or directories to take the same group as the directory they are created in. This is needed to preserve the ownership of newly-created files and directories.
