Linux Using associative array for comparison

Hello together,

i make something wrong... I want an array that contains information to associate it for further processing.

Here is something from my bash... You will know, what I'm trying to do.
I have to point out in advance, that the variable $SYSOS is changing and not as static as in my example:

Code:
myuser@server ~ % declare -A os
myuser@server ~ % os["release-notes-sles-11.3"]=" SuSE Linux SLES11-SP3"
myuser@server ~ % echo $os["release-notes-sles-11.3"]
 SuSE Linux SLES11-SP3
myuser@server ~ % SYSOS="release-notes-sles-11.3"
myuser@server ~ % echo $SYSOS
release-notes-sles-11.3
myuser@server ~ % echo $os[$SYSOS]

myuser@server ~ %

As you can see I want to read the array "dynamically", but it does not work.
It does not even work with echo $os[${SYSOS}]

Can someone help me please?


Thank you very much and best greetings,
Dennis

asort - Sort an array and maintain index association

SYNOPSIS
bool asort (array &$array, [int $sort_flags = SORT_REGULAR]) DESCRIPTION
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant. PARAMETERS
o $array - The input array. o $sort_flags - You may modify the behavior of the sort using the optional parameter $sort_flags, for details see sort(3). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 asort(3) example <?php $fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple"); asort($fruits); foreach ($fruits as $key => $val) { echo "$key = $val "; } ?> The above example will output: c = apple b = banana d = lemon a = orange The fruits have been sorted in alphabetical order, and the index associated with each element has been maintained.
