## Basic Unix Tutorial - prerequisite for AFNI bootcamp

    This tutorial is a very brief introduction to Unix.  It is based
    on the AFNI_data6 directory tree, and can be found there.

    Goals:
       - be able to navigate directories and peruse contents
       - run afni in the background
       - understand some basics of shell scripts and variables

    Notes:
       - commands to type will be on a yellow background
       - practice typing commands exactly as they appear, rather than
         using a copy-and-paste approach ("practice makes better")

    Background:

          0. What are Unix, tcsh and AFNI?

          1. Opening a command terminal for the first time

    Tutorials:

          0. Install AFNI and the AFNI_data6 class data tree

          1. Practice the cd and ls commands

          2. Foreground and background

          3. (very) Light intro to shell scripts

          4. Shell variables

    tutorial pages 0 through 3 are prerequisite for the AFNI bootcamp
