CS 5984: Computation for the Life Sciences

Fall Semester, 2002
Homework Assignment 1

The point value (if any) of each step is shown in square brackets [ ]. As you will find out from the assignment, all solutions will be emailed to the instructor. Therefore, there is nothing to turn in.

This homework (the two emails to the instructor) is due at 5:00PM on September 6, 2002. No late homework will be accepted.

Everything in this assignment occurs through a Linux shell.

1. Log into your Linux account on arabidopsis.cs.vt.edu.

2. Make a directory where you will work on Homework 1. Change to that directory.

3. Get the file identity.txt using the wget command, as follows:

   wget http://courses.cs.vt.edu/~cs4life/handouts/homeworks/identity.txt
   

4. Open identity.txt with the pico command. Replace the lower-case text with the appropriate information. Save your changes in the same file.

5. [15] Run the pine command and start a new outgoing email. Read identity.txt into the body of the email. Make the subject identity.txt and send the email to heath@vt.edu.

6. Get the Perl script identity_script using the wget command, as follows:

   wget http://courses.cs.vt.edu/~cs4life/handouts/homeworks/identity_script
   

   Make it executable with the following command:

   chmod u+x identity_script
   

7. [15] Run the identify_script command and answer the questions that are asked. The Perl script will send your answers via an email to heath@vt.edu.
