Note that this exercise is meant to be performed in the lab with the
assistance of your instructor. However, if you do not finish, you
must finish on your own time.
- 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, type oitcleaner
at the linux prompt.
- Getting Ready to Use the xemacs 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/d/b/dblock/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
- Use the xemacs Text Editor to Create an Autobiography
You will be using the xemacs text editor to create a file called
mybio.txt. The file will contain a brief autobiography about you
as follows:
- Begin by stating your name, major, and class standing (e.g., sophomore).
- 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,
- why you chose your major,
- the best college course you have had so far and why.
To create your autobiography file, do the following.
- Enter the emacs editor by typing: xemacs 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.
- Backspace or Delete key will delete characters to the left of
the cursor.
- <Ctrl>+d will delete characters under the cursor.
- 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
- 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 are also going
to send a copy of the email to yourself.
To accomplish this, do the following.
- Enter pine by typing: pine
- If this is the first time you are opening pine you will probably
see a screen that welcomes you to pine. You should type the
letter 'e' to exit the welcome message screen.
- Next, the pine main menu should appear. Type: c to begin
composing a new e-mail.
- Next to To:, type: oratsi2@gl.umbc.edu
- Next to Cc:, type: yourusername@umbc.edu
- Next to Attchmnt:, type: mybio.txt
- Next to Subject:, type: Autobiography for your name
- In the Message Text area, type: CMSC104 autobiography
followed by your name.
- 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.
- Log Off the Linux System
To log off of the system, type logout. Make sure you
log off of the computer as well.
