Shell Programming and Scripting

Could anyone tell me how to write a C shell script according to the following requirement.

Write a C shell script convertmin which will read in a number, thought of as representing minutes, and print out the number of hours/minutes it represents so:

Note: you are required to check exception cases: such as negative number, whether the input is numeric, etc

$ convertmin
Enter a number of minutes:
128

Result
128 minutes is 2 hours and 8 minutes

Ringo,

You might want to look at the rules of this forum. Once you have, please explain the business application of the script you are trying to write.

Most of the time we don't write scripts for people but we do help when they have a script that doesn't work. Most of the time we can tell if a question has to do with business or a business application. I get the feeling this is not one of those times.
