CSC161 2010F, Class 02: Linux Basics

Overview:
* Review.
* Lab!

Admin:
* Assignment 1 is ready.
* For today, you should work together, but have a neighboring computer
  ready.  (There are some exercises that require a partner.)
* Questions: The legendary extra credit checklist

Review: What did we learn on Friday?
* The history command in the terminal, which shows you your recent
  commands, prefaced by the command number
  * You can redo a command with !number
* When does it get reset?
  * And how would you find that out?
    * Experimentally:
      * It seems to stay around for awhile
    * I *think* that when you log out, it gets stored
    * ASSIGNMENT!
* cat 
* tabs autocomplete

Big picture from lecture: There is more than one way to think about
algorithm design

Big picture from lab: Although we are accustomed to Graphical User
Interfaces (GUI), at times we want to interact with the computer
textually, and it may even be helpful to do so.
