how/where umask is defined on a Ubuntu server system

Question

I am wondering how - or more exactly where - umask is defined on a stock Ubuntu server system.

I have reactivated the root account. Here's the respective default umask for root and normal users:

Nomal User:

$ umask
0002

Root User

$ umask
0022

On RHEL/CentOS, these values are defined in /etc/bashrc and then in the individual ~/.bashrc files. How does Ubuntu handle this?

Answer 1

umask value is set in "/etc/login.defs" but you can override it in bashrc.
