UNIX for Dummies Questions & Answers

Does anyone know how I can write a script file that reads 15 numbers and can find the average, maximum and minimum of the 15 numbers.
I'm new to UNIX 1 month into it, and (no) this is not for homework.

I'm reading UNIX unbounded and trying the practice questions and I've been working on this for a few days and still can't figure it out. I'm completely out of answers with this one. These script commands are killing me.

Any advice would greatly be appreciated.


Thanks

What OS and version and what scripting lanugage are you using might be helpful for those of us that haven't used that book. And posting what you have tried and the errors you have gotten would be helpful.

I believe it's Redhat Linux, is there a way for me to know what type of UNIX I'm using?

Post what you have so far and maybe someone can figure out what's wrong with it.

So far I was able to figure out a little bit and it seems to work.
I think.

I'm still unsure of how to find the average of 10 numbers and not sure if I'm doing this correctly. I want to be able to play around with the while loop and if statements so I'll be able to write a script that reads 10 numbers and can find a max, min and average. Any advice would be appreciated. I'm terrible with math so this is making things even harder for me.

Here is what I have so far.

ksh-2.04$ cat>maximum
echo "Enter 2 Numbers Below to Find Which One is The Maximum Number: "
read num1 num2
if [ $num1 -gt $num2 ]
then
echo "Number1: $num1 is the Maximum"
else
echo "Number2: $num2 is the Maximum"

fi

exit

ksh-2.04$ sh maximum
Enter 2 Numbers Below to Find Which One is The Maximum Number:
32
Number2: is the Maximum
ksh-2.04$

Thanks

That'll work fine by sperating your read in two seperate lines

Code:

#!/bin/sh
echo " Enter first number "

read num1

echo " Enter second number "

read num2

if [ $num1 -gt $num2 ]
then
echo "Number1: $num1 is the Maximum"
else
echo "Number2: $num2 is the Maximum"

fi

exit

I'm going to try that, that's viraven.
