Using Getopt Option
Hi

I need to use getopt option and I have no idea what it is or how to use it.

I need to use it on this awk script:

Code:
awk -F, -v cellid="$1" -v paramval="$2" -v oldfile="$3" -v newfile="$4" '$2==cellid{$3=newvalue}1' OFS="," $3 > $4

I tried reading up on it but I just confuse myself more.

Please help.

Here is my code so far:

Code:
awk -F, -v cellid="$1" -v paramval="$2" -v oldfile="$3" -v newfile="$4" '$2==cellid{$3=newvalue}1' OFS="," $3 > $4
function displayUsage()
{
                echo "Usage: [--usage]";
}
function displayHelp()
{
                displayUsage
                echo ""
                echo " -v       variable"
                echo " -i       cellid"
}
while getopts "vi:" option
do
        case $option in
                v )
                        echo "-v variable"
                        ;;
                i )     echo "-i cellid"
                        ;;
                u )     displayUsage;;
                h )     displayHelp;;
        esac
done

Can getopt simply display what the variable is? Like a definition of the variable?
