Due Date:

Midnight, Tuesday February 11

Note that late projects will NOT be accepted.

Point Value:

This project is worth 20 points.

Objectives:

To become familiar with

• using Tera Term to log on to and off of the UMBC gl Linux system (linux.gl.umbc.edu),
• checking your disk quota and deleting unnecessary files,
• the basic use of the emacs text editor, and
• the basic use of the pine e-mail client.

Note that this exercise is meant to be performed in the lab with the assistance of your instructor and TA. However, if you do not finish, you must finish on your own time.

Resources:

• Summary of Common emacs/xemacs Commands (attached)
• The pine help command (enter pine and type: ?)

Assignment:

1. Log On to the Linux System

   Log on to the Linux system by following the instructions on the attached "Logging On and Off Using Tera Term" sheet.

2. Check Your Disk Quota and Clean Your Directory

   OIT allocates a fixed amount of disk space (called your "disk quota") to each of the gl system users. It is a good habit to check your disk quota from time to time to make sure that you are not coming close to your allocation. To do this, type: quota -v

   If you have already used a large portion of your quota (e.g., 90% or higher), you should delete unnecessary files. To do this, you must copy a file called cleaner into your directory. To copy this file, type

   cp /afs/umbc.edu/users/s/m/smitchel/pub/cleaner . Note that the final period is part of the command and must be typed. Also, you only need to copy this file into your directory once. Check that the cleaner file is in your directory by typing: ls

   Run the program by typing: cleaner

   You should now have more disk space available.

3. Getting Ready to Use the emacs Text Editor

   Before you begin the next part of this exercise, you need to copy another file into your directory. This file is called .emacs and activates certain emacs features (do not worry about what features for now). To copy the file, type

   cp /afs/umbc.edu/users/s/m/smitchel/pub/.emacs . Note that the final period is part of the command and must be typed. To check that the file is now in your directory, type: ls -a

4. Use the emacs Text Editor to Create an Autobiography

   You will be using the emacs text editor to create a file called mybio.txt. The file will contain a brief autobiography about you as follows:

   1. Begin by stating your name, major, and class standing (e.g., sophomore).

   2. Then, write a paragraph or two telling me a little bit about yourself. Tell me
      • where you are from and why you chose UMBC for your education,
      • which programming languages you know, if any,
      • which operating systems you are familiar with, if any, and
      • why you are taking this course.
      Do not leave out any of this information!

   To create your autobiography file, do the following.

   • Enter the emacs editor by typing: emacs mybio.txt
   • Simply type in the information specified above. Edit any mistakes using the Backspace or Delete key to backspace and the Ctl-d sequence to delete a character. (Use the attached "Summary of Common emacs/xemacs Commands" as a reference. I have placed arrows next to the "more important" commands.)
   • Save your work by typing Ctl-x and then Ctl-s.
   • Exit emacs by typing Ctl-x and then Ctl-c.
   • You will know that you have exited emacs and are again talking to the Linux system if you see the linux1[#]% or linux2[#]% or linux3[#]% prompt.
   • You can check that the file mybio.txt is in your directory by typing: ls

5. Use the pine E-mail Client to Send an E-mail With an Attachment

   You are now going to use pine to send an e-mail to me that has the mybio.txt file that you created as an attachment. You will also send a carbon copy (cc) to our TA, Gaurav Jolly.

   To accomplish this, do the following.

   • Enter pine by typing: pine
   • The pine main menu should appear. Type: c to begin composing a new e-mail.
   • Next to To:, type: smitchel@csee.umbc.edu
   • Next to Cc:, type: jolly1@umbc.edu
   • Next to Attchmnt:, type: mybio.txt
   • Next to Subject:, type: Autobiography for your name
   • In the Message Text area, type: Here is my autobiography! followed by your name and CMSC 104, Section 0301.
   • To send the e-mail, type Ctl-x and then y.
   • Type: q to exit out of pine.
   • You are done when you receive the system prompt of linux1[#]% or linux2[#]% or linux3[#]% back.

6. Log Off the Linux System

   When you are done with this exercise, log off of the Linux system by following the instructions on the attached "Logging On and Off Using Tera Term" sheet.
