Sep 7 lecture notes -- web perl 

 -- getting started --

 * Don't underestimate the power of 
   typing what you want into Google. (e.g. "apple X11 download")

 * Do look at my notes from last year's perl course for links.
   See the link in the Resources section of the course web page.

 * Basic skills and concepts
   * your own directory on the campus server 
   * remote login (ssh)
     * command line :  ls, cd, man
     * file permissions : rwx is "read", "write", "eXecute".  See "man chmod"
   * your html/ directory and http://www.marlboro.edu/~username/

 * perl executable and a good text editor

    * unix server (akbar.marlboro.edu, cs.marlboro.edu)
      * command line
        $ ssh cs.marlboro.edu    OR   ssh -X cs.marlboro.edu
        $ ls
	$ cd
	$ whereis perl
	$ emacs OR xemacs OR vi OR vim OR pico     # editors
	$ vi
	
    * mac
      * Fink is highly recommended.
      * As is X11 from Apple, and the Developer tools from Apple.
      * perl should already be installed.
      * ditto for a unix command line prompt, via Utilities/Terminal
      * You can get Fink to install emacs, xemacs, ...
        (Did I mention that it's highly recommended?)

    * windows
      * Cygwin is highly recommended.
        * As is The X11 part, Cygwin.x (x.cygwin.com)
    
  * Some basic perl
      * how to run it
      * use strict; use warnings;
      * $scalar $variables : numbers, strings, references, ...
      * @array @variables : ($any, "old", "stuff", 1, 3 )
      * many, many built-in functions
      * many variations on legal syntax
      * understandin scalar vs array context is crucial
      * lots of kinds of quotes and expression matching constructs
      * common "gotchas" :
        * semicolon at ends of line
	* except subroutine definition

 -- for those who know perl -- 

  * see the alternative assignments

    * perl objects , references, and all that

    * install/configure/run an apache web server
