I've just started a class on scripting and have run into a wall. Can anyone help/hint with this?
Write a shell script to ask for name, major, and expected graduation year. The output should be split onto 3 lines.
Write a shell script to find the sum, the average, and the product of 4 integers entered by the user. The output should be split onto 3 lines
Write a shell script to check whether or not the provided year is a leap year. The output should be the word yes or no
Write a shell script to display all usernames that contains a given pattern of characters. You will need to use the cut and grep commands against the /etc/passwd file to do this.
They won't help do your homework for you (see the LQ rules about homework/classwork). You need to post what you have tried using the code tags too to make it readable.
Below is a cut and paste from the LQ Welcome link, as well as a reminder about the LQ Rules
Quote:
Do not post homework assignments verbatim. We're happy to assist if you have specific questions or have hit a stumbling point, however. Let us know what you've already tried and what references you have used (including class notes, books, and searches) and we'll do our best to help. Keep in mind that your instructor might also be an LQ member.
Hello and welcome to LQ. You were pointed here because a fellow LQ member feels the thread you started doesn't contain enough information to enable us to help you. We understand that Linux can be intimidating for new members, and we really do want to help. That said, please understand that LQ is not a help desk, customer service line for a product you purchased or willing to do your homework (although we are happy to assist you with specifics, if you show some effort of your own!). We're a 100% volunteer organization that wants to help you help yourself.
Here are a couple tips that will enable us to help you moving forward:
When asking a question, be sure to provide as many relevant details as possible. You should include the distribution and version you're using, along with hardware details, application version and exact error messages where applicable.
Using a descriptive title will vastly increase the number of members who see your thread, and therefore make a response significantly more likely.
If you're actively troubleshooting an issue you should also include any steps you've already taken.
You may want to include how what you are experiencing differs from what you expected to experience.
Before posting, have you used the search function to ensure your question hasn't been asked before?
You can edit your post by clicking the EDIT button in the bottom right corner of your message.
If you are unwilling or unable to ask questions in a manner that allows us to help you, it's unlikely our community will be able to provide you a solution. Unfortunately, serial offenders who show wanton disregard for this request after multiple pointers may be asked to seek help elsewhere. We truly hope that isn't necessary, and assure you Linux and Open Source are extremely rewarding and well worth the learning curve in the long run.

Well, I think we both know there's no education in the second kick of a mule.
If the OP continues on like this, he'll discover soon enough the error of his ways, moments after his boss in all likelihood.
best way to figure out a script in writing it is, one step at a time. Lets look at all of the steps you will be needing to do to get a complete script to do what you need it to do.
1.
Quote:
input needs:
name
major
expected graduation year
output needs:
print to screen
should be split onto 3 lines
another separate script, or within the same one. Does not matter really, just need to have it do one first then the next.
2.
Quote:
input:
4 integers
output:
print to screen
sum of 4 integers
average of 4 integers
split into 3 lines off of two outputs, does not compute.
another script or within the same script.

Quote:
function:
return yes|no if input year is a leap year or not
print to screen
another script or within the same script.
4.
Quote:
function that writes to screen all usernames that contain a given pattern
using characters, by means of cut and grep. Data to use is /etc/passwd (file)
that is a lot of homework you want to take credit for others doing the work for you. Do you not think?
Remember what I said in the beginning of this post, take it one step at a time.
rule of thumb:
if you can do it in the command line then it can be done in a script.
the use of a function is my take on it, not the teachers. He or she may or may not like the student showing any kind of initiative.
