Write array contents to file

Hi,

I have a bash script that currently holds some data. I am trying to write all the contents to a file called temp.txt.

I am using
Code:
echo ${array[@]} > temp.txt

The problem that I am experiencing is that the elements are being written horizontally in the file. I want them written vertically.

This code writes it correctly but it appends the file which I don't want it to do.

Code:
for j in "${array[@]}"
do
  echo $j >>temp.txt
done

By changing the line to echo $j > temp.txt, the file only contains the last array element.



Example

array[0] = 5
array[1] = 6
array[2] = 1
array[3] = 3

File contents

5 6 1 3

What I want is

5
6
1
3

Thanks.
