The /etc/profile configuration file is used to configure the bash shell environment and startup programs when a user logs on. This is the system-wide default configuration file for all users who log into the system.

This file is also located at: /usr/local/etc/profile on some systems.

     The settings created in the /etc/profile configuration file can be overriden by users by placing the the .bash_profile configuration file into their home directory.

Note: Redhat overrides /etc/profile with /etc/bashrc and the .bash_profile in the users home directory with .bashrc.

     The /.bashrc configuration file is a non-interactive setup file. The /.bash_profile configuration file is interactive. The non-interactive type sets environment variables permanently from interative.
