Setting up Startup Files: .profile and .bashrc

Reference: Chapter 10, p.318-319

All file references are to files in your home directory ($HOME) on ACADUNIX.

.profile:

    ACADUNIX uses the Korn shell as your login shell.  (The Korn shell
    is a Bourne-type shell similar to BASH.)  The Korn shell reads
    ("sources") the file ".profile" only once when you first log in.
    You can put things in this file that need to be done exactly once
    at login and that are inherited by other shells:

     - set PATH and/or TERM
     - set umask
     - set erase character (backspace)
     - set your prompt PS1 (and export it: export PS1)

    Any aliases you define here will apply only to the Korn shell at
    login, not to any other shells you start.  If you find that a
    nested shell is not inheriting PATH, TERM, or PS1, you must
    "export" the variable (p.323), e.g. "export PS1".

    The last thing you can put in this file is "bash", to execute the
    bash shell when you first log in.

.bashrc:

    The BASH shell reads ("sources") .bashrc when it first starts up.
    Every new BASH shell reads this file.  Put things in this file
    that don't get inherited from parent shells:

     - set your bash aliases

    Any aliases you define here will apply only to all BASH shells,
    not to the original login shell (a Korn shell).
