When  bash is invoked as an interactive login

       shell, or as a non-inter- active shell with the

       --login option, it first reads and executes com-

       mands  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 ~/.bashrc, if that file exists.  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 ~/.bashrc.
