Linux Script Issue
 

Hello, I am trying to figure this out and really could use some help. Below is what i'm being asked to do and below that is a script I had to write the previous week, according to what I need to do it's an extension to what I've already done.I have been fighting a huge cold and I really could use help in this and look forward to a reply, my email is cf4610@gmail.com.

Ty,

Chris


Case – switch 2, 9 points (3 if it runs correctly, 5 if all components are included and 1 for
comments) and yes we live in a partial credit world.
This project is an extension of the case and switch assignment from last week. We have
used all the elements of this script in prior homework projects, puzzles and/or scripts.
This time around everything is a choice in a case switch script.
Your shell script will use case and switch and should include the following elements:
some kind of conditional test to proceed (date, verify users is logged, etc)
request the user’s name (save as a variable to be used at exit)
a counter that counts the number of total choices made by the user
a use of the cut command (cut a field from you friends list or some other file)
an option to run 5 different commands (ls, who, ping etc) and
on exiting the script, echo the user’s name, user inputs (you will want to save
these as varialbes and how many choices the user made).
Comments MUST be included in the script! Your script should be easy for anyone to run
without the need of prompting from you, the developer.
Email a copy and leave an executable copy in the appropriate homework directory.
Remember, by reading your comments I should be able to see exactly what your script is
doing (or suppose to do). Why use comments? Comments force you to think through the
scripting process. Scripting could be considered a mechanical process of converting your
comments into UNIX commands.

So, what is it exactly that you have problems with?
Show debug output, or a thorough explanation of your problem, instead of posting the assignment.
And please edit your post and put the code in BB code tags for readability.

Hello, not sure if I did the BB code right, and I'm not fully sure what I'm being asked to do. What I attached was an example of what i'm being asked to do, so maybe you can help me alter it ? I never have been able to wrap my brain around this script making, so i'm desperate for help but I will try to answer any questions you have. Also my intro to programming has me doing something similar could I shoot you what I have with that to see what you think?

Tyvm,

Chris

You got that part right.


If you don't understand your assignment then ask your teacher for clarification. If OTOH you mean what you should do here then tell us which of the 6 items on your list you work on right now, what doesn't work and why you think it doesn't work.

* Just so there'll be no misunderstanding: do not expect us provide you with a complete, grading-ready homework assignment. Like your assignments goal is to force you to think through the scripting process we try to achieve the same by asking questions. Learning takes time.
