What follows is from the bash man page, hope it helps.

 When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands

       from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that

       order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is

       started to inhibit this behavior.

       When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

       When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these

Do you need help?

       files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file

       instead of /etc/bash.bashrc and ~/.bashrc.

       When bash is started non-interactively, to run a shell script, for example, it looks for the variable BASH_ENV in the environment, expands its

       value if it appears there, and uses the expanded value as the name of a file to read and execute. Bash behaves as if the following command were

       executed:
              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
       but the value of the PATH variable is not used to search for the file
