Introduction to Unix
--------------------

  login: a270xxxx     <-- from list in class

  eddie:

    ^ The `prompt' which usually says your machine name


Change your password

  eddie: passwd
  Changing password for a270xxxx
  Enter login password: --------        <-- type it

Unix

* You have a `current directory', just like DOS.

Commands

  ls                 list
  cd x               change directory to x
  cp x y             copy file x to file y
  mkdir x            make directory called x
  more x             show file x, pausing between screenfuls.  Press
                     the spacebar to scroll to the next screen.
  rm x               remove file x
  emacs              *the* editor

Editing a program

  use emacs!         % emacs &

                     Type C-h t in emacs for a tutorial

Emacs gives
  - file and command completion
  - colour highlights
  - automatic indenting and formatting for C
  - GDB debugger incorporated
  - rmail

See the programs in ~jstewart/270:

  vars.c           (debugging example)
  oddeven.c        (formatting example)
  print.c          (editing example)

Execute

  % cp -r ~jstewart/.emacs* ~

to get emacs initialization files.  If you use a monochrome terminal,
do

  % cp -r ~jstewart/.emacs* ~
  % cp -r ~/.emacs-nocolour ~/.emacs
