Hi guys,

I have a few questions to ask and would appreciate all relevant input. This might be easy for some but can somebody help answer some of these;

1. Write a shell script that takes three numbers as arguments and outputs to the screen the sum of these numbers.
2. Write a shell script that reads three numbers and outputs to the screen the sum of these numbers.
3. Write a shell script that takes three numbers as arguments and outputs to the screen the maximum of these numbers.
4. Write a shell script that takes three numbers as arguments and outputs to the screen the three numbers in sorted order. You are not allowed to use the "internal built-in sort function".
5. Suppose the file employee.txt contains the following lines:

100 Thomas Manager Sales $5,000 Auckland
200 Jason Developer Technology $5,500 Auckland
300 Sanjay Sysadmin Technology $7,000 Hamilton
400 Nisha Manager Marketing $9,500 Hamilton
500 Randy DBA Technology $6,000 Hamilton

a. Write an awk that prints the second and the last element in each line.
b. Write an awk that prints the number of lines where the fourth field is Technology.
c. Write an awk that prints prints the lines where the sixth field is Hamilton.

Cheers

Do we get your course credit?

Are you asking for these scripts to be written for you, or are you asking for help with a specific problem you are having?

Generally, I would say that yes, all of these scripts are possible.

1. & 2. Use the 'bc' or 'dc' command
3. Use comparison operators in BASH
4. Use comparison operators in BASH, in a loop
5a. Yes, awk can do these functions.

If you have a more specific question, maybe post that.

Yea Mate you can get the course credit if you feel obliged to it, If your not willing to help dont other commenting, I said all relevant input would be appreciated. Cheers

Hi,
I think you should read the forum rules [1] regarding homework questions.
