Filter command arguments

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Execute command with integer list arguments such as myScript 8 7 2 3.
Take those arguments and square all of them one by one, each iteration print out the result. At the end print out the total sum of the squared values.

2. Relevant commands, code, scripts, algorithms:

Code:

# Error handling if the argument list is empty or contains string instead of integers.

if [ $# = 0 ]
then
        echo "Usage $0 -integer-list"
        exit 1
elif [ $@ = [^9-0] ]
then
        echo "No Strings are allowed."
fi

I want to output an error message when characters are found inside the argument list.

3. The attempts at a solution (include all code and scripts):

Code:

#!/bin/sh
# File:                         power
# Author:                      
# Student ID:                   
# Created:                      6/23/2012
# Purpose:                      
# Description:                  This program uses the integer list provides
#                               as command arguments and evaluates the square 
#                               numbers of all of them. At the end of the 
#                               script the sum of all the squared numbers is 
#                               printed to the screen
#
#
#
#


# Error handling if the argument list is empty or contains string instead of integers.

if [ $# = 0 ]
then
        echo "Usage $0 -integer-list"
        exit 1
elif [ $@ = [^9-0] ]
then
        echo "No Strings are allowed."
fi

total=0
power=0

# Function used for summation of the squared number list.
sum()
{
        total=`expr $total + $power`    # Sum the total value.
}

# Iterates through the argument list.
for num in $@
do
        power=`expr $num \* $num`               # Evaluate the square for the current argument.
        echo "$num squared equals $power"       # Print to screen the square of the argument.
        sum             # Call the sum function to sum the square values togehter.      
done

# Prints the result of the sum function
echo "Total of squared numbers = $total"

lmfsetup

lmfsetup(8) System Manager's Manual lmfsetup(8)

Name
lmfsetup - License Management Facility PAK registration script

Syntax
/etc/lmfsetup [ template ]

Description
The script allows you to register data supplied by a Product Authorization Key (PAK). The script prompts you for the data associated with
each of the fields on a PAK. When all the data has been entered, the License Management Facility (LMF) ensures there are entries against
all the mandatory fields, and that the Checksum validates all the license data. If the data has been entered correctly, the PAK is regis-
tered in the License Database. If the data has been entered incorrectly, the appropriate error message is displayed and you are given the
opportunity to re-enter the data.

The template option allows you to register license data from templates in A template containing a partially complete PAK is created by some
products as part of their installation process. The script only prompts you for data on the fields that are empty in the template. If the
script cannot find the specified template in it searches the current directory.

The script is provided as an alternative to the command. This displays a template, which includes the fields on the PAK, and invokes an
editor so that you can add the license data to the appropriate field. The command also allows errors to be corrected without having to re-
enter all the data.
