The /etc/bashrc File
The /etc/bashrc is referred to as the /etc/bash.bashrc on some Linux distros. It contains system-wide functions and aliases including other configurations that apply to all system users.
If the system administrator allows users to select from the numerous different shells for their login shell, it is a good idea to put all bash-specific system configurations in this file.
