Sharing Write Permission
For more than one user to be able to write to the same directory it will be necessary to grant write permission to a group they share in common. The following example grants shared write permission to /var/www to the group “webmasters”.
sudo chgrp -R webmasters /var/www
sudo find /var/www -type d -exec chmod g=rwxs “{}” \;
sudo find /var/www -type f -exec chmod g=rws “{}” \;
sudo find /var/www -type d -exec chmod g=rwxs “{}” \;
sudo find /var/www -type f -exec chmod g=rws “{}” \;
EXAMPLES
chgrp staff /u
Change the group of /u to “staff”.
chgrp -hR staff /u
Change the group of /u and subfiles to “staff”.
