Apply default permission to directory (From http://unix.stackexchange.com/questions/1314/how-to-set-default-file-permissions-for-all-folders-files-in-a-directory)

applypermissionubuntu

chmod g+s <directory>  //set gid 
setfacl -d -m g::rwx /<directory>  //set group to rwx default 
setfacl -d -m o::rx /<directory>   //set other
Next we can verify:

getfacl /<directory>
Output:

# file: ../<directory>/
# owner: <user>
# group: media
# flags: -s-
user::rwx
group::rwx
other::r-x
default:user::rwx
default:group::rwx
default:other::r-x
