See Code and Example in My Repository : Bhansali's Shell Maps

It has 2 Libraries Created for Shell :
1. Map ( Map.h )
2. Ordered Map ( Ordered_Map.h )

Example.sh shows usage where I am Importing it like we do in C++/Java

It has at least Following functionalities :

1. Creating Map/Ordered Map

2. Putting Values in It Manually By Using Put Method ( map.put Key Value )

3. Getting Values Back ( map.get Key Value )

4. Remove Values from Map ( map.remove Key )

5. Display Entire Map By Iterating it on All Indices

6. Displaying All Keys

7. Clearing Map ( Make it Empty )

8. Populating it with a Properties File ( map.populate Hamari.properties )

9. Get Value By Index, If it is OrderedMap ( map.getByIndex Index )
