Typical warning function

This function is useful to display and record the warning count. You may later use the count as failure exit code.

function warning()
{
	echo "$@" 1>&2
	((WARNING_COUNT++))
}

Example:

#! /bin/bash

function warning()
{
	echo "$@" 1>&2
	((WARNING_COUNT++))
}
	
warning this is first warning
warning second warning
warning last warning
echo "I gave you $WARNING_COUNT warnings"
