Hi. I have created a script that works perfect but I am now told that I could have done it better, but how?
This is an example of how I did mine:

#!/bin/bash
#
function users
{

echo "1. Password file"
echo
echo "Enter num: "

read usernumber

if [ $usernumber -eq 1 ]
then
cat /etc/passwd

else if [ $usernumber -eq 2 ]
then
cat etc/passwd
fi
fi
I have been told that I shouldn't have done it using else if but what other ways are there of doing it?

Thanks
