Introduction to Linux UNIX
DCOM 142 Final Project
Overview: This final is a practical based activity covering
areas of Linux from throughout the semester. Read each section
carefully and thoroughly before executing the tasks within the
section. Remember, you have access to the any book(s),
self-prepared notes, the internet, and the system's help, man, and
info pages.
Some tasks will require root access using the sudo command.
This Final will assume that you are logged in as the student
user.
When completed properly, you should not see any error messages
from the commands run. If you are seeing errors, check to make sure
you are performing the task correctly.
Remember that Linux commands and file/directory names are case
sensitive. Full credit will not be awarded if files or directories
are spelled incorrectly.
Graphical tools can be used but will make it harder for me to
give partial credit.
Be certain you are working in your own Virtual Machine as the
student user!

Section 3 –Searching Inside Files
Note: This section requires the
/usr/share/dict/words file. If the file
/usr/share/dict/words does not exist, run the following
command:
sudo yum install words
or
sudo yum -y install words
--disablerepo=my-internal-repo
1.
Find how many lines are
inside of the /usr/share/dict/words file. Save the
number of lines to a file named words.txt in your
home directory.
2.
Search the
/usr/share/dict/words file for all words
containing “egg-white”. Append all words
containing “egg-white” to a file named
words.txt in your home directory.
3.
Search the
/usr/share/dict/words file for all words containing
“veggies”. Count and append and save the number of
words containing “veggies” to a file named
words.txt in your home directory.
Attach contents of words.txt file screen shot stored in
your home directory.
Section 4 – Script 2

Create a script called
user.sh. This script should:
a) prompt the user to enter their
username
b) check to see if the username is the
currently logged in username. If it is not, the script should print
an error message and exit. If it is the correct user, the script
should print a welcome message to the user.
2. Save the file as
user.sh and run this script and make sure it works
as expected.
3.
Re-run this script with
user.sh | tee user.txt so that the output is both
shown on the screen and saved to ~/user.txt <>
Required for grading:
Paste the screen shot of the contents of user.sh and output of
running user.sh
