How to set default file permissions for all folders/files in a directory?

Question

I want to set a folder such that anything created within it (directories, files) inherit default permissions and group.

Lets call the group "media". And also, the folders/files created within the directory should have g+rw automatically.

Answer 1

I found it: Applying default permissions

From the article:

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

You can run find and give it chmod +whatever as execute argument.
