Goal: Lots of clerical stuff, and linux directory heirarchy

Homework: 
Make a tree diagram of your home computer's directory structure. This will differ for windows and mac users. Include the important locations that you save your files. You cannot put in all of the directories, but you can get an idea of what your folder structure looks like. Bring it in tomorrow, with your name PRINTED on it. 
If you want to make it look good, try a free diagram site like: https://www.gliffy.com

Do Now: (1-4)
1 - How do you change directly to your home directory?
2 - If your current directory is /your.name/Documents , what commands could you type ine the command line to change to /your.name/Desktop?
3 - If you were a superuser that had to create tom's directory to look like this:
What sequence of terminal commands would create this directory structure? List the commands in order. Assume you start in /home/
4 - What are two ways you can open a file in any operating system you have used?

New Commands:
  • cp sourceFileName targetFileName - copy will make a copy of the source file, and name it target.
  • mv sourceFileName targetFileName - mv will move the source file to the target file.
  • touch fileName - will modify the timestamp of a file to the current time, if the file doesn't exist it will create an empty file.
  • sourceFileName and targetFileName can be a full path e.g. cp ~/test.temp /home/other/what.txt

Important Links: (hand copy into your notebooks, then bookmark in your browsers)
