Hello batchenr,

I think you probably want to use an Associative Array, i.e an unordered list of key to value pairs. Have a look in the man bash pages for the basic information and skip forward to the Arrays section, about 90% of the way down on my display.

Associative arrays are created using declare -A array_name and you add and use values like this:-
Code:
#!/bin/bash

declare -A array_name

array_name["Key1"]="Value1"
array_name["Key2"]="Value2"
array_name["Key3"]="Value3"
array_name["Key4"]="Value4"

for testkey in Key3 Key1
do
   echo "${array_name[$testkey]}"
done

..... and this should give the output Value3 then Value1


Is this what you need, or have I missed the point?


Kind regards,
Robin
