Here is another method of adding elements in the array.. It works best with korn shell

set -A array_example 1 2 3 4 5
i=0
echo ${array_example[$i]}

One way to merge two arrays:

#existing array
existing=(item1, item2, item3);

#items to merge (including an item requiring correct quoting)
merge=(item4 item5 "${item6}*");

count=${#existing[@]};
num_new_items=${#merge[@]};
# this loop appends items to the end of the array
for (( i=0;i<$num_new_items;i++)); do
echo ${i};
existing[$count]=${merge[${i}]};
let count+=1;
done

count=${#existing[@]}
for (( i=0;i<$count;i++)); do
echo ${existing[${i}]};
done

Reading a line, while preseriving whitespaces seems har dto do from a file

You can do it this way:
<pre>
cat $file | while read line; do
echo "$line";
done
</pre>
