7.2.3.4. .bash_login example

The ~/.bash_login file defines default file protection by setting the umask value, see Section 3.4.2.2. The ~/.bashrc file is used to define a bunch of user-specific aliases and functions and personal environment variables. It first reads /etc/bashrc, which describes the default prompt (PS1) and the default umask value. After that, you can add your own settings. If no ~/.bashrc exists, /etc/bashrc is read by default.
