Stephen G. Kochan, Patrick Wood,
Shell Programming in Unix, Linux and OS X: The Fourth
Edition of Unix Shell Programming, (4th Ed.)
Optional: Hahn, Harley, Harley Hahn's Guide to Unix and Linux, ©2009 Harley Hahn, Pub. by McGraw-Hill. ISBN # 978-0-07-313361-4.
(This course is 3 credit hours long.)
This course is intended for students who have mastered the basic Linux/Unix
operating environment and who would like to read and understand the various
administrative scripts, and to write scripts to automate day-to-day
This course is designed to teach students the skills they need to
effectively read, write and debug shell scripts.
This course explores in detail the Bash shell scripting language.
Major topics covered include reading, writing, modifying, and debugging
shell scripts, the shell environment, regular expressions, text filtering
The basic Unix/Linux environment is taught in the course CTS 1106 (Introduction to Unix / Linux).
|Objectives:|| The student will demonstrate a knowledge of the following
topics through objective tests, hands-on activities, and/or projects:
|Prerequisites:||CTS 1106 (Introduction to Unix / Linux), or permission of the instructor. Students enrolled in a degree or college credit certificate program program must complete all prerequisites. Note! HCC registration computers may not check for prerequisites before allowing you to enroll. Be certain you have all required prerequisites or you won't have much of a chance of success. Also you may be dropped from the class.|
|Facilities:|| Assignments must be completed on
You will need your own flash disk, writing materials, and three Scantron 882–E or 882–ES forms. You can use HawkNet (WebAdvisor) or Florida Virtual Campus to obtain your final grade for the course. You can use your assigned Hawkmail email address if you wish to discuss your grades via email. (Note, it is possible to setup your Hawkmail account to forward all received emails to some outside email account; but you still must send mail from Hawkmail to discuss grades.)
Most college systems use a single sign-on user ID, known as HCC “NetID”. Visit netid.hccfl.edu to register and to update your credentials. (Your initial password is your uppercase first name initial, lowercase last name initial, and your seven digit student ID number.) Note the quickest way to resolve login issues is the HCC Live Web Portal (hcclive.hccfl.edu).
The college provides wireless network connections for students and guests
on Dale Mabry campus.
For students, select the network
Hawk Alert text messaging service allows you to receive important information regarding campus closures or emergencies. You may also sign up for financial aid notifications and registration and payment deadlines. This is a free service, although some fees may be applied by your cellular service provider or plan for text messages. To sign up, or for more information, visit www.hccfl.edu/hawkalert/.
HCC's Student Assistance Program (SAP) offers resources tailored to student life, providing you with the right tools to help you through some of life's toughest challenges. The college has contracted Baycare Health Management to provide free, professional, confidential counseling by telephone and in person. A wide range of topics may be addressed through this program, including mental health counseling, budgeting, and financial concerns. Please call 800-878-5470 or send email to firstname.lastname@example.org for further information.
A=90-100, B=80-89, C=70-79, D=65-69,
Projects will be assigned from the class web page at various times.
You will have sufficient time to complete the projects,
at least a week but usually two weeks.
Although there may be in-class group exercises, you must work
individually on projects, typically outside of regular class hours,
except when a project is designated as a group project.
(Currently, all projects are designated group projects.)
You may work together in small (two to four people) groups on group projects,
provided the names of all who worked together are listed.
Each student must still submit their own copy of the assignment.
Projects are graded on the following scale:
A = 95% (Excellent: Good design with good comments, style, and extras)
Minor extras worth +5 points, minor omissions or poor design worth -5.
Projects are not graded when turned in. They are graded all at once, sometime after the project deadline has passed (usually the following weekend). Every effort will be make to grade projects within a week of the due date, or as soon thereafter as possible. (See also submitting assignments below.)
Projects should be submitted by email to
Please use a subject such as “Shell Scripting Project #1
Submission” so I can tell which emails are submitted work.
Send only one assignment per email message.
Email your projects by copy-and-paste into your mail program.
Please do not use email attachments, except
when noted in the assignment directions.
If possible, use the “text” and not the
“HTML” mode of your email program.
Do not send any email to
In the event a student submits more than once for the same assignment, I will ignore all but the last one received up to the deadline. Assignments submitted after the deadline will not count toward your grade except as allowed by the course late policy. Also, you cannot resubmit an assignment once it has been graded.
The HCC email server automatically accepts and
silently discards email with certain types of attachments.
If you must send email to my Internet (non-YborStudent) email
account please avoid using any attachments, but especially
To send email with a “
To avoid having your submitted work rejected as “spam”, you can use Hawkmail365 to send email to professors. This doesn't always work either! If you are having difficulties with this email address, use MyHCC email.)
If you have an email problem you may turn in a printout instead. Be sure your name is clearly written on the top of any pages turned in. Please staple multiple pages together (at the upper left).
Always keep a backup copy of your submitted projects, until you are certain they have been received and graded correctly.
