Question

i have a shell script for putting values into an array. The script is working fine for me. The problem is, if i put the array inside a for loop (between do and done), and when i try to print the array length outised the loop,i.e, after done, the values are not getting updated. Here is the sameple code;

function _read_value
{
    count=0
    array[0]="hi" 
    for ///some condition
    do
        count++
        array[count]="hello"
    done
    echo ${#array[@]
}

When i try to print the length of the array at the end, it is showing the length as 1.
Any help would be appreciated.

I made some small changes in your script and its updating values and the count also comes fine.(I made change in count increment and in loop)

#!/bin/bash
function read_value
{
    count=0
    while [ $count -le 5 ]
    do
        array[count]="hello"
        count=`expr $count + 1`
    done
    echo ${array[@]}
    echo ${#array[@]}
}

read_value
