Question: should we start on the lab?

Answer: I'll send email each week when the "new lab" is available.
   My meetings with Dan Roche, your TA are Friday mornings,
   so look for new labs to become available Friday Afternoons or over the
   weekend before your Monday labs.


If you want to get a good head start on the class, read chapers 1-3 in Savitch.

Labs will generally be due one week later than the day you first see
them in lab, at 11:55pm.



A Unix question:

I have some files in a directory under the current directory (.)
The files are in the directory:

 ./02.07/an.incorrect.program

How do I copy them with one command into:

 ./02.09/an.incorrect.program

Answer:

 cp ./02.07/an.incorrect.program/* 02.09/an.incorrect.program

Notes:
 (1)   the ./ at the beginning is optional

 (2) this command only copies "plain old files".

 (3) if we wanted to be able to copy directories living under 
        02.07/an.incorrect.program
     along with all their contents, we would use the following command:


 cp -r  ./02.07/an.incorrect.program/* 02.09/an.incorrect.program


 cp -r    recursive copy
 chmod -R    recursive "change file permissions"
