How to set the default file permissions on ALL newly created files in linux

Question

My question is similar to this:

https://stackoverflow.com/questions/228534/linux-default-file-permission

but there is no scp/ftp client involved and that question looks abandoned. Simply put: I want to be able to, at some global level decree that all newly created files will never have world writable permissions (0775).

I tried putting a umask 02 in /etc/profile then in my bash_profile but it only works for scripts or new files that I create in a shell. It doesn't work for files that another binary creates. Is there anyway to have all new files that are created?

Answer 1

umask is what you want...

Answer 2

What you want is the UMASK setting in the /etc/login.defs file.
