Linux – How to Set Default File Permissions for All Folders/Files in a Directory

directorylinuxpermissions

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.

I found it: Applying default permissions

From the article:

  1. Set the setgid bit, so that files/folder under <directory> will be created with the same group as <directory>

    chmod g+s <directory>

  2. Set the default ACLs for the group and other

    setfacl -d -m g::rwx /<directory>
setfacl -d -m o::rx /<directory>

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
