How To Inherit Parent Directories Group

Question

I have a directory /applications which is owned by root and group git.

The problem is when I create a new directory inside /applications, its owned by root and group root, not group git. How do I make new directories inside /applications inherit the group git instead of root?

Answer 1

You have to enable setgid on it:

chmod g+s /applications

From that point all the files and directories will be owned by group git
