I'm trying to expand my array by adding another value onto the end of it, thus adding a new index and upping the length of the array by one. I am iterating through two arrays, and trying to get one array into the index of the other. I'm use 4.1.5 release of bash and most of the methods I have tried are outdated.

This is my code...

Code:

for ((i=1; i<=${COUNT1}; i++))
do
	for ((j=1; j<=${COUNT2}; j++))
	do
		if [[ ${MAIN_ARRAY[i]} != ${SECOND_ARRAY[${j}]} ]]
		then
                      #Put the value of SECOND_ARRAY in MAIN_ARRAY
		fi
	done
done

I originally tried the += method and it did not work.

Code:

${ARRAY}+=${NEW_VALUE[${i}]}

Then I tried adding one to the length of the array.

Code:

q=`echo ${#ARRAY[@]}`
let q++ 
ARRAY[${q}]=${SECOND_ARRAY[${j}]}

Again, I am trying to iterate through two arrays, and if the the value of the second array is not in the first, put it in there at the end.
