CPT 180 Bash Assignment
Directions
Using the following guidelines, create a Bash program.
1. You will be using the CPT180Stuff folder from Chapter 8 for this assignment.
2. Create a Bash program named workWithFiles3.sh
3. Add three comment lines at the top of the program that contain:
a. Program Name
. Program Description
c. Programmer's Name (You)
4. Write code that will do the following:
a. Using an if statement, determine if both the dognames.txt file and the catnames.txt file
exist. If both files exist, the program should complete steps b – e below. If either file does
not exist, the program should print out the message "Unable to access one or more files".
. Print the contents of the dognames.txt file.
c. Print the contents of the catnames.txt file.
d. Add two cat names to the catnames.txt file. You can pick the names. The example output
elow shows the names Sassy and Lucy added.
e. Print the contents of the catnames.txt file.
5. Submit the workWithFiles3.sh file into the Bash Assignment Submission Folder.
Hints
1. The echo command when used to append to a file adds a newline after the item is appended.
2. When using Cygwin, you can access the Windows drives by using the cygdrive device. For
example, if your CPT180Stuff folder is located in the root directory of the E drive, you could access
the dognames.txt file from your Bash program by using the path:
cygdrive/e/cpt180stuff/pets/dogs/dognames.txt

Hints for the bash script
Posted Jul 16, XXXXXXXXXX:00 AM
I know the script is a little way off, but a couple of comments.
First, you are using a completely different scripting
language. Make certain you read up on bash before you
start. Most students do well if they got the logic for appending
the names to the catnames.txt file. The bash script is just that
ut using the bash shell rather than Python.
Be certain you use the same directory structure for this script,
e.g. /cpt180stuff/pets/cats/. Don't write a script that assumes
the files are somewhere else.
Make certain you check for the existence of BOTH the dognames
and catnames files. This was a requirement for the chapter 8/9
assignment; it is the same for the bash assignment.
Bash is really picky about spaces in an if-statement. If you are
getting e
ors on your if, make certain the
aces have spaces
efore and after.
Don't forget to print the contents of the catnames file both
efore and after you have appended the names. A lot of
students miss that for some reason.
Good luck.
CPT 180 PowerShell Assignment

3. Add three comment lines at the top of the program that contain:
a. Program Name
. Program Description
c. Programmer's Name (You)

a. Using an if statement, determine if both the dognames.txt file and the catnames.txt file
exist. If both files exist, the program should complete steps b – h below. If either file does
not exist, the program should print out the message "Unable to access one or more files".
. Get the contents of the file named dognames.txt in the CPT180Stuff\pets\dogs folder.
c. Print the contents of the file.
d. Get the contents of the file named catnames.txt in the CPT180Stuff\pets\cats folder.
e. Print the contents of the file.
f. Add two cat names to the catnames.txt file. You can pick the names. The example output
elow shows the names Sammy and Luna added.
g. Get the contents of the file named catnames.txt.
h. Print the contents of the file.
5. Submit the workWithFiles4.ps1 file into the PowerShell Assignment Submission Folder.
