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

kernel_kate

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.

Good Linux question — answering as the UphillTech team:

I found it: Applying default permissions From the article: Set the setgid bit, so that files/folder under <directory> will be created with the same group as <directory> chmod g+s <directory> 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
